holoviews.mpl Package#

`mpl` Package#

holoviews.plotting.mpl.set_style(key)[source]#: Select a style by name, e.g. set_style(‘default’). To revert to the previous style use the key ‘unset’ or False.

`annotation` Module#

class holoviews.plotting.mpl.annotation.ABLine2D(slope, intercept, *args, **kwargs)[source]#

Bases: Line2D

Draw a line based on its slope and y-intercept. Additional arguments are passed to the <matplotlib.lines.Line2D> constructor.

add_callback(func)[source]#

Add a callback function that will be called whenever one of the .Artist’s properties changes.

Parameters#

funccallable

The callback function. It must have the signature:

def func(artist: Artist) -> Any

where artist is the calling .Artist. Return values may exist but are ignored.

Returns#

int: The observer id associated with the callback. This id can be used for removing the callback with .remove_callback later.

Parameters#

mouseevent : ~matplotlib.backend_bases.MouseEvent

Returns#

containsbool

Whether any values are within the radius.

detailsdict

A dictionary {'ind': pointlist}, where pointlist is a list of points of the line that are within the pickradius around the event position.

TODO: sort returned indices by distance

convert_xunits(x)[source]#

Convert x using the unit type of the xaxis.

If the artist is not contained in an Axes or if the xaxis does not have units, x itself is returned.

convert_yunits(y)[source]#

Convert y using the unit type of the yaxis.

If the artist is not contained in an Axes or if the yaxis does not have units, y itself is returned.

draw(renderer)[source]#

Draw the Artist (and its children) using the given renderer.

This has no effect if the artist is not visible (.Artist.get_visible returns False).

Parameters#

renderer : ~matplotlib.backend_bases.RendererBase subclass.

Notes#

This method is overridden in the Artist subclasses.

findobj(match=None, include_self=True)[source]#

Find artist objects.

Recursively find all .Artist instances contained in the artist.

Parameters#

match

A filter criterion for the matches. This can be

None: Return all objects contained in artist.
A function with signature def match(artist: Artist) -> bool. The result will only contain artists for which the function returns True.
A class instance: e.g., .Line2D. The result will only contain artists of this class or its subclasses (isinstance check).

include_selfbool

Include self in the list to be checked for a match.

Returns#

list of .Artist

format_cursor_data(data)[source]#

Return a string representation of data.

Note

This method is intended to be overridden by artist subclasses. As an end-user of Matplotlib you will most likely not call this method yourself.

The default implementation converts ints and floats and arrays of ints and floats into a comma-separated string enclosed in square brackets, unless the artist has an associated colorbar, in which case scalar values are formatted using the colorbar’s formatter.

Parameters#

event : ~matplotlib.backend_bases.MouseEvent

Returns#

tuple or None

get_snap()[source]#

Return the snap setting.

See .set_snap for details.

get_solid_capstyle()[source]#

Return the .CapStyle for solid lines.

Parameters#

renderer~matplotlib.backend_bases.RendererBase subclass, optional: renderer that will be used to draw the figures (i.e. fig.canvas.get_renderer())

Returns#

.Bbox or None: The enclosing bounding box (in figure pixel coordinates). Returns None if clipping results in no intersection.

get_transform()[source]#: Return the .Transform instance used by this artist.

get_transformed_clip_path_and_affine()[source]#: Return the clip path with the non-affine part of its transformation applied, and the remaining affine part of its transformation.

get_url()[source]#: Return the url.

get_visible()[source]#: Return the visibility.

get_window_extent(renderer=None)[source]#

Get the artist’s bounding box in display space.

The bounding box’ width and height are nonnegative.

Subclasses should override for inclusion in the bounding box “tight” calculation. Default is to return an empty bounding box at 0, 0.

Be careful when using this function, the results will not update if the artist window extent of the artist changes. The extent can change due to any changes in the transform stack, such as changing the Axes limits, the figure size, or the canvas used (as is done when saving a figure). This can lead to unexpected behavior where interactive figures will look fine on the screen, but will save incorrectly.

get_xdata(orig=True)[source]#

Return the xdata.

If orig is True, return the original data, else the processed data.

get_xydata()[source]#: Return the xy data as a (N, 2) array.

get_ydata(orig=True)[source]#

Return the ydata.

If orig is True, return the original data, else the processed data.

get_zorder()[source]#: Return the artist’s zorder.

have_units()[source]#: Return whether units are set on any axis.

is_dashed()[source]#

Return whether line has a dashed linestyle.

A custom linestyle is assumed to be dashed, we do not inspect the onoffseq directly.

Parameters#

filter_funccallable: A filter function, which takes a (m, n, depth) float array and a dpi value, and returns a (m, n, depth) array and two offsets from the bottom left corner of the image

set_alpha(alpha)[source]#

Set the alpha value used for blending - not supported on all backends.

Parameters#

alphascalar or None: alpha must be within the 0-1 range, inclusive.

set_animated(b)[source]#

Set whether the artist is intended to be used in an animation.

If True, the artist is excluded from regular drawing of the figure. You have to call .Figure.draw_artist / .Axes.draw_artist explicitly on the artist. This approach is used to speed up animations using blitting.

See also matplotlib.animation and blitting.

Parameters#

b : bool

set_antialiased(b)[source]#: Set whether to use antialiased rendering.

Parameters#

b : bool

set_c(color)[source]#: Alias for set_color.

set_clip_box(clipbox)[source]#

Set the artist’s clip .Bbox.

Parameters#

clipbox~matplotlib.transforms.BboxBase or None: Will typically be created from a .TransformedBbox. For instance, TransformedBbox(Bbox([[0, 0], [1, 1]]), ax.transAxes) is the default clipping for an artist added to an Axes.

set_clip_on(b)[source]#

Set whether the artist uses clipping.

When False, artists will be visible outside the Axes which can lead to unexpected results.

Parameters#

b : bool

set_clip_path(path, transform=None)[source]#

Set the artist’s clip path.

Parameters#

path~matplotlib.patches.Patch or .Path or .TransformedPath or None: The clip path. If given a .Path, transform must be provided as well. If None, a previously set clip path is removed.
transform~matplotlib.transforms.Transform, optional: Only used if path is a .Path, in which case the given .Path is converted to a .TransformedPath using transform.

Notes#

For efficiency, if path is a .Rectangle this method will set the clipping box to the corresponding rectangle and set the clipping path to None.

For technical reasons (support of ~.Artist.set), a tuple (path, transform) is also accepted as a single positional parameter.

set_color(color)[source]#: Set the color of the line.

Parameters#

color : :mpltype:`color`

set_dash_capstyle(s)[source]#

How to draw the end caps if the line is ~Line2D.is_dashed.

The default capstyle is :rc:`lines.dash_capstyle`.

Parameters#

s : .CapStyle or {‘butt’, ‘projecting’, ‘round’}

set_dash_joinstyle(s)[source]#

How to join segments of the line if it ~Line2D.is_dashed.

The default joinstyle is :rc:`lines.dash_joinstyle`.

Parameters#

s : .JoinStyle or {‘miter’, ‘round’, ‘bevel’}

set_dashes(seq)[source]#

Set the dash sequence.

The dash sequence is a sequence of floats of even length describing the length of dashes and spaces in points.

For example, (5, 2, 1, 2) describes a sequence of 5 point and 1 point dashes separated by 2 point spaces.

See also ~.Line2D.set_gapcolor, which allows those spaces to be filled with a color.

Parameters#

seqsequence of floats (on/off ink in points) or (None, None): If seq is empty or (None, None), the linestyle will be set to solid.

set_data(*args)[source]#: Set the x and y data.

Parameters#

*args : (2, N) array or two 1D arrays

See Also#

set_xdata set_ydata

set_drawstyle(drawstyle)[source]#

Set the drawstyle of the plot.

The drawstyle determines how the points are connected.

Parameters#

drawstyle{‘default’, ‘steps’, ‘steps-pre’, ‘steps-mid’, ‘steps-post’}, default: ‘default’

For ‘default’, the points are connected with straight lines.

The steps variants connect the points with step-like lines, i.e. horizontal lines with vertical steps. They differ in the location of the step:

‘steps-pre’: The step is at the beginning of the line segment, i.e. the line will be at the y-value of point to the right.
‘steps-mid’: The step is halfway between the points.
‘steps-post: The step is at the end of the line segment, i.e. the line will be at the y-value of the point to the left.
‘steps’ is equal to ‘steps-pre’ and is maintained for backward-compatibility.

For examples see /gallery/lines_bars_and_markers/step_demo.

set_ds(drawstyle)[source]#: Alias for set_drawstyle.

set_figure(fig)[source]#: Set the .Figure instance the artist belongs to.

Parameters#

Set the marker fill style.

Parameters#

fs{‘full’, ‘left’, ‘right’, ‘bottom’, ‘top’, ‘none’}

Possible values:

‘full’: Fill the whole marker with the markerfacecolor.
‘left’, ‘right’, ‘bottom’, ‘top’: Fill the marker half at the given side with the markerfacecolor. The other half of the marker is filled with markerfacecoloralt.
‘none’: No filling.

For examples see marker_fill_styles.

set_gapcolor(gapcolor)[source]#

Set a color to fill the gaps in the dashed line style.

Note

Striped lines are created by drawing two interleaved dashed lines. There can be overlaps between those two, which may result in artifacts when using transparency.

This functionality is experimental and may change.

Parameters#

gapcolor:mpltype:`color` or None: The color with which to fill the gaps. If None, the gaps are unfilled.

set_gid(gid)[source]#: Set the (group) id for the artist.

Parameters#

gid : str

set_in_layout(in_layout)[source]#: Set if artist is to be included in layout calculations, E.g. constrainedlayout_guide, .Figure.tight_layout(), and fig.savefig(fname, bbox_inches='tight').

set_label(s)[source]#

Set a label that will be displayed in the legend.

Parameters#

sobject: s will be converted to a string by calling str.

where onoffseq is an even length tuple of on and off ink in points. See also set_dashes().

For examples see /gallery/lines_bars_and_markers/linestyles.

set_linewidth(w)[source]#

Set the line width in points.

Parameters#

wfloat: Line width, in points.

set_ls(ls)[source]#: Alias for set_linestyle.

set_lw(w)[source]#: Alias for set_linewidth.

set_marker(marker)[source]#

Set the line marker.

Parameters#

markermarker style string, ~.path.Path or ~.markers.MarkerStyle: See ~matplotlib.markers for full description of possible arguments.

set_markeredgecolor(ec)[source]#: Set the marker edge color.

Parameters#

ec : :mpltype:`color`

set_markeredgewidth(ew)[source]#

Set the marker edge width in points.

Parameters#

ewfloat: Marker edge width, in points.

set_markerfacecolor(fc)[source]#: Set the marker face color.

Parameters#

fc : :mpltype:`color`

set_markerfacecoloralt(fc)[source]#: Set the alternate marker face color.

Parameters#

fc : :mpltype:`color`

set_markersize(sz)[source]#

Set the marker size in points.

Parameters#

szfloat: Marker size, in points.

set_markevery(every)[source]#

Set the markevery property to subsample the plot when using markers.

e.g., if every=5, every 5-th marker will be plotted.

Parameters#

everyNone or int or (int, int) or slice or list[int] or float or (float, float) or list[bool]

Which markers to plot.

every=None: every point will be plotted.
every=N: every N-th marker will be plotted starting with marker 0.
every=(start, N): every N-th marker, starting at index start, will be plotted.
every=slice(start, end, N): every N-th marker, starting at index start, up to but not including index end, will be plotted.
every=[i, j, m, ...]: only markers at the given indices will be plotted.
every=[True, False, True, ...]: only positions that are True will be plotted. The list must have the same length as the data points.
every=0.1, (i.e. a float): markers will be spaced at approximately equal visual distances along the line; the distance along the line between markers is determined by multiplying the display-coordinate distance of the Axes bounding-box diagonal by the value of every.
every=(0.5, 0.1) (i.e. a length-2 tuple of float): similar to every=0.1 but the first marker will be offset along the line by 0.5 multiplied by the display-coordinate-diagonal-distance along the line.

For examples see /gallery/lines_bars_and_markers/markevery_demo.

Notes#

Setting markevery will still only draw markers at actual data points. While the float argument form aims for uniform visual spacing, it has to coerce from the ideal spacing to the nearest available data point. Depending on the number and distribution of data points, the result may still not look evenly spaced.

When using a start offset to specify the first marker, the offset will be from the first data point which may be different from the first the visible data point if the plot is zoomed in.

If zooming in on a plot when using float arguments then the actual data points that have markers will change because the distance between markers is always determined from the display-coordinates axes-bounding-box-diagonal regardless of the actual axes data limits.

set_mec(ec)[source]#: Alias for set_markeredgecolor.

set_mew(ew)[source]#: Alias for set_markeredgewidth.

set_mfc(fc)[source]#: Alias for set_markerfacecolor.

set_mouseover(mouseover)[source]#: Set whether this artist is queried for custom context information when the mouse cursor moves over it.

Parameters#

mouseover : bool

See Also#

get_cursor_data .ToolCursorPosition .NavigationToolbar2

set_ms(sz)[source]#: Alias for set_markersize.

set_path_effects(path_effects)[source]#: Set the path effects.

Parameters#

path_effects : list of .AbstractPathEffect

set_picker(p)[source]#

Set the event picker details for the line.

Parameters#

pfloat or callable[[Artist, Event], tuple[bool, dict]]: If a float, it is used as the pick radius in points.

set_pickradius(pickradius)[source]#

Set the pick radius used for containment tests.

See .contains for more details.

Parameters#

pickradiusfloat: Pick radius, in points.

set_rasterized(rasterized)[source]#

Force rasterized (bitmap) drawing for vector graphics output.

Rasterized drawing is not supported by all artists. If you try to enable this on an artist that does not support it, the command has no effect and a warning will be issued.

This setting is ignored for pixel-based output.

See also /gallery/misc/rasterization_demo.

Parameters#

rasterized : bool

set_sketch_params(scale=None, length=None, randomness=None)[source]#

Set the sketch parameters.

Parameters#

scalefloat, optional

The amplitude of the wiggle perpendicular to the source line, in pixels. If scale is None, or not provided, no sketch filter will be provided.

lengthfloat, optional

The length of the wiggle along the line, in pixels (default 128.0)

randomnessfloat, optional

The scale factor by which the length is shrunken or expanded (default 16.0)

The PGF backend uses this argument as an RNG seed and not as described above. Using the same seed yields the same random shape.

set_snap(snap)[source]#

Set the snapping behavior.

Snapping aligns positions with the pixel grid, which results in clearer images. For example, if a black line of 1px width was defined at a position in between two pixels, the resulting image would contain the interpolated value of that line in the pixel grid, which would be a grey value on both adjacent pixel positions. In contrast, snapping will move the line to the nearest integer pixel value, so that the resulting image will really contain a 1px wide black line.

Snapping is currently only supported by the Agg and MacOSX backends.

Parameters#

snapbool or None

Possible values:

True: Snap vertices to the nearest pixel center.
False: Do not modify vertex positions.
None: (auto) If the path contains only rectilinear line segments, round to the nearest pixel center.

set_solid_capstyle(s)[source]#

How to draw the end caps if the line is solid (not ~Line2D.is_dashed)

The default capstyle is :rc:`lines.solid_capstyle`.

Parameters#

s : .CapStyle or {‘butt’, ‘projecting’, ‘round’}

set_solid_joinstyle(s)[source]#

How to join segments if the line is solid (not ~Line2D.is_dashed).

The default joinstyle is :rc:`lines.solid_joinstyle`.

Parameters#

s : .JoinStyle or {‘miter’, ‘round’, ‘bevel’}

set_transform(t)[source]#: Set the artist transform.

Parameters#

t : ~matplotlib.transforms.Transform

set_url(url)[source]#: Set the url for the artist.

Parameters#

url : str

set_visible(b)[source]#: Set the artist’s visibility.

set_xdata(x)[source]#: Set the data array for x.

Parameters#

x : 1D array

See Also#

set_data set_ydata

set_ydata(y)[source]#: Set the data array for y.

Parameters#

y : 1D array

See Also#

set_data set_xdata

set_zorder(level)[source]#: Set the zorder for the artist. Artists with lower zorder values are drawn first.

Parameters#

level : float

property stale#: Whether the artist is ‘stale’ and needs to be re-drawn for the output to match the internal state of the artist.

property sticky_edges#

x and y sticky edge lists for autoscaling.

When performing autoscaling, if a data limit coincides with a value in the corresponding sticky_edges list, then no margin will be added–the view limit “sticks” to the edge. A typical use case is histograms, where one usually expects no margin on the bottom edge (0) of the histogram.

Moreover, margin expansion “bumps” against sticky edges and cannot cross them. For example, if the upper data limit is 1.0, the upper view limit computed by simple margin application is 1.2, but there is a sticky edge at 1.1, then the actual upper view limit will be 1.1.

This attribute cannot be assigned to; however, the x and y lists can be modified in place as needed.

Examples#

>>> artist.sticky_edges.x[:] = (xmin, xmax)
>>> artist.sticky_edges.y[:] = (ymin, ymax)

update(props)[source]#: Update this artist’s properties from the dict props.

Parameters#

props : dict

anim(start=0, stop=None, fps=30)[source]#: Method to return a matplotlib animation. The start and stop frames may be specified as well as the fps.

cleanup()[source]#: Cleans up references to the plot on the attached Stream subscribers.

compute_ranges(obj, key, ranges)[source]#: Given an object, a specific key, and the normalization options, this method will find the specified normalization options on the appropriate OptionTree, group the elements according to the selected normalization option (i.e. either per frame or over the whole animation) and finally compute the dimension ranges in each group. The new set of ranges is returned.

get_aspect(xspan, yspan)[source]#: Computes the aspect ratio of the plot

get_extents(element, ranges, range_type='combined', dimension=None, xdim=None, ydim=None, zdim=None, lims_as_soft_ranges=False, **kwargs)[source]#

Gets the extents for the axes from the current Element. The globally computed ranges can optionally override the extents.

The extents are computed by combining the data ranges, extents and dimension ranges. Each of these can be obtained individually by setting the range_type to one of:

‘data’: Just the data ranges
‘extents’: Element.extents
‘soft’: Dimension.soft_range values
‘hard’: Dimension.range values

To obtain the combined range, which includes range padding the default may be used:

‘combined’: All the range types combined and padding applied

This allows Overlay plots to obtain each range and combine them appropriately for all the objects in the overlay.

If lims_as_soft_ranges is set to True, the xlim and ylim will be treated as soft ranges instead of the default case as hard ranges while computing the extents. This is used e.g. when apply_hard_bounds is True and xlim/ylim is set, in which case we limit the initial viewable range to xlim/ylim, but allow navigation up to the abs max between the data range and xlim/ylim.

get_padding(obj, extents)[source]#: Computes padding along the axes taking into account the plot aspect.

update_frame(*args, **kwargs)[source]#

Set the plot(s) to the given frame number. Operates by manipulating the matplotlib objects held in the self._handles dictionary.

teardown_handles()[source]#: If no custom update_handles method is supplied this method is called to tear down any previous handles before replacing them.

traverse(fn=None, specs=None, full_breadth=True)[source]#: Traverses any nested DimensionedPlot returning a list of all plots that match the specs. The specs should be supplied as a list of either Plot types or callables, which should return a boolean given the plot class.

update(key)[source]#: Update the internal state of the Plot to represent the given key tuple (where integers represent frames). Returns this state.

update_frame(*args, **kwargs)[source]#

Set the plot(s) to the given frame number. Operates by manipulating the matplotlib objects held in the self._handles dictionary.

If n is greater than the number of available frames, update using the last available frame.

update_handles(key, axis, annotation, ranges, style)[source]#: Update the elements of the plot.

class holoviews.plotting.mpl.annotation.HLinesAnnotationPlot(annotation, **params)[source]#

Bases: _SyntheticAnnotationPlot

Parameters inherited from:

anim(start=0, stop=None, fps=30)[source]#: Method to return a matplotlib animation. The start and stop frames may be specified as well as the fps.

cleanup()[source]#: Cleans up references to the plot on the attached Stream subscribers.

compute_ranges(obj, key, ranges)[source]#: Given an object, a specific key, and the normalization options, this method will find the specified normalization options on the appropriate OptionTree, group the elements according to the selected normalization option (i.e. either per frame or over the whole animation) and finally compute the dimension ranges in each group. The new set of ranges is returned.

get_aspect(xspan, yspan)[source]#: Computes the aspect ratio of the plot

get_extents(element, ranges=None, range_type='combined', **kwargs)[source]#

Gets the extents for the axes from the current Element. The globally computed ranges can optionally override the extents.

The extents are computed by combining the data ranges, extents and dimension ranges. Each of these can be obtained individually by setting the range_type to one of:

‘data’: Just the data ranges
‘extents’: Element.extents
‘soft’: Dimension.soft_range values
‘hard’: Dimension.range values

To obtain the combined range, which includes range padding the default may be used:

‘combined’: All the range types combined and padding applied

This allows Overlay plots to obtain each range and combine them appropriately for all the objects in the overlay.

If lims_as_soft_ranges is set to True, the xlim and ylim will be treated as soft ranges instead of the default case as hard ranges while computing the extents. This is used e.g. when apply_hard_bounds is True and xlim/ylim is set, in which case we limit the initial viewable range to xlim/ylim, but allow navigation up to the abs max between the data range and xlim/ylim.

anim(start=0, stop=None, fps=30)[source]#: Method to return a matplotlib animation. The start and stop frames may be specified as well as the fps.

cleanup()[source]#: Cleans up references to the plot on the attached Stream subscribers.

compute_ranges(obj, key, ranges)[source]#: Given an object, a specific key, and the normalization options, this method will find the specified normalization options on the appropriate OptionTree, group the elements according to the selected normalization option (i.e. either per frame or over the whole animation) and finally compute the dimension ranges in each group. The new set of ranges is returned.

get_aspect(xspan, yspan)[source]#: Computes the aspect ratio of the plot

get_extents(element, ranges=None, range_type='combined', **kwargs)[source]#

Gets the extents for the axes from the current Element. The globally computed ranges can optionally override the extents.

The extents are computed by combining the data ranges, extents and dimension ranges. Each of these can be obtained individually by setting the range_type to one of:

‘data’: Just the data ranges
‘extents’: Element.extents

‘hard’: Dimension.range values

To obtain the combined range, which includes range padding the default may be used:

‘combined’: All the range types combined and padding applied

This allows Overlay plots to obtain each range and combine them appropriately for all the objects in the overlay.

If lims_as_soft_ranges is set to True, the xlim and ylim will be treated as soft ranges instead of the default case as hard ranges while computing the extents. This is used e.g. when apply_hard_bounds is True and xlim/ylim is set, in which case we limit the initial viewable range to xlim/ylim, but allow navigation up to the abs max between the data range and xlim/ylim.

`chart` Module#

class holoviews.plotting.mpl.chart.AreaPlot(element, **params)[source]#

Bases: AreaMixin, ChartPlot

Parameters inherited from:

padding = param.ClassSelector(allow_refs=False, class_=(<class ‘int’>, <class ‘float’>, <class ‘tuple’>), default=(0, 0.1), label=’Padding’, nested_refs=False, rx=<param.reactive.reactive_ops object at 0x17847ee10>): Fraction by which to increase auto-ranged extents to make datapoints more visible around borders. To compute padding, the axis whose screen size is largest is chosen, and the range of that axis is increased by the specified fraction along each axis. Other axes are then padded ensuring that the amount of screen space devoted to padding is equal for all axes. If specified as a tuple, the int or float values in the tuple will be used for padding in each axis, in order (x,y or x,y,z). For example, for padding=0.2 on a 800x800-pixel plot, an x-axis with the range [0,10] will be padded by 20% to be [-1,11], while a y-axis with a range [0,1000] will be padded to be [-100,1100], which should make the padding be approximately the same number of pixels. But if the same plot is changed to have a height of only 200, the y-range will then be [-400,1400] so that the y-axis padding will still match that of the x-axis. It is also possible to declare non-equal padding value for the lower and upper bound of an axis by supplying nested tuples, e.g. padding=(0.1, (0, 0.1)) will pad the x-axis lower and upper bound as well as the y-axis upper bound by a fraction of 0.1 while the y-axis lower bound is not padded at all.

If the dimension is set to cyclic in the dim_info it will rotate the curve so that minimum y values are at the minimum x value to make the plots easier to interpret.

Parameters inherited from:

padding = param.ClassSelector(allow_refs=False, class_=(<class ‘int’>, <class ‘float’>, <class ‘tuple’>), default=(0, 0.1), label=’Padding’, nested_refs=False, rx=<param.reactive.reactive_ops object at 0x1785a02d0>): Fraction by which to increase auto-ranged extents to make datapoints more visible around borders. To compute padding, the axis whose screen size is largest is chosen, and the range of that axis is increased by the specified fraction along each axis. Other axes are then padded ensuring that the amount of screen space devoted to padding is equal for all axes. If specified as a tuple, the int or float values in the tuple will be used for padding in each axis, in order (x,y or x,y,z).

But if the same plot is changed to have a height of only 200, the y-range will then be [-400,1400] so that the y-axis padding will still match that of the x-axis. It is also possible to declare non-equal padding value for the lower and upper bound of an axis by supplying nested tuples, e.g. padding=(0.1, (0, 0.1)) will pad the x-axis lower and upper bound as well as the y-axis upper bound by a fraction of 0.1 while the y-axis lower bound is not padded at all.

The new set of ranges is returned.

get_aspect(xspan, yspan)[source]#: Computes the aspect ratio of the plot

get_extents(element, ranges, range_type='combined', dimension=None, xdim=None, ydim=None, zdim=None, lims_as_soft_ranges=False, **kwargs)[source]#

Gets the extents for the axes from the current Element. The globally computed ranges can optionally override the extents.

The extents are computed by combining the data ranges, extents and dimension ranges. Each of these can be obtained individually by setting the range_type to one of:

‘data’: Just the data ranges
‘extents’: Element.extents
‘soft’: Dimension.soft_range values
‘hard’: Dimension.range values

To obtain the combined range, which includes range padding the default may be used:

‘combined’: All the range types combined and padding applied

This allows Overlay plots to obtain each range and combine them appropriately for all the objects in the overlay.

If lims_as_soft_ranges is set to True, the xlim and ylim will be treated as soft ranges instead of the default case as hard ranges while computing the extents. This is used e.g. when apply_hard_bounds is True and xlim/ylim is set, in which case we limit the initial viewable range to xlim/ylim, but allow navigation up to the abs max between the data range and xlim/ylim.

class holoviews.plotting.mpl.chart.SpikesPlot(*args, **kwargs)[source]#

Bases: SpikesMixin, PathPlot, ColorbarPlot

Parameters inherited from:

padding = param.ClassSelector(allow_refs=False, class_=(<class ‘int’>, <class ‘float’>, <class ‘tuple’>), default=(0, 0.1), label=’Padding’, nested_refs=False, rx=<param.reactive.reactive_ops object at 0x178860490>): Fraction by which to increase auto-ranged extents to make datapoints more visible around borders. To compute padding, the axis whose screen size is largest is chosen, and the range of that axis is increased by the specified fraction along each axis. Other axes are then padded ensuring that the amount of screen space devoted to padding is equal for all axes. If specified as a tuple, the int or float values in the tuple will be used for padding in each axis, in order (x,y or x,y,z). For example, for padding=0.2 on a 800x800-pixel plot, an x-axis with the range [0,10] will be padded by 20% to be [-1,11], while a y-axis with a range [0,1000] will be padded to be [-100,1100], which should make the padding be approximately the same number of pixels. But if the same plot is changed to have a height of only 200, the y-range will then be [-400,1400] so that the y-axis padding will still match that of the x-axis. It is also possible to declare non-equal padding value for the lower and upper bound of an axis by supplying nested tuples, e.g. padding=(0.1, (0, 0.1)) will pad the x-axis lower and upper bound as well as the y-axis upper bound by a fraction of 0.1 while the y-axis lower bound is not padded at all.
aspect = param.Parameter(allow_refs=False, default=’square’, label=’Aspect’, nested_refs=False, rx=<param.reactive.reactive_ops object at 0x178861b90>): The aspect ratio mode of the plot. Allows setting an explicit aspect ratio as width/height as well as ‘square’ and ‘equal’ options.

compute_ranges(obj, key, ranges)[source]#: Given an object, a specific key, and the normalization options, this method will find the specified normalization options on the appropriate OptionTree, group the elements according to the selected normalization option (i.e. either per frame or over the whole animation) and finally compute the dimension ranges in each group. The new set of ranges is returned.

get_aspect(xspan, yspan)[source]#: Computes the aspect ratio of the plot

get_extents(element, ranges, range_type='combined', **kwargs)[source]#

Gets the extents for the axes from the current Element. The globally computed ranges can optionally override the extents.

The extents are computed by combining the data ranges, extents and dimension ranges. Each of these can be obtained individually by setting the range_type to one of:

‘data’: Just the data ranges
‘extents’: Element.extents
‘soft’: Dimension.soft_range values
‘hard’: Dimension.range values

To obtain the combined range, which includes range padding the default may be used:

‘combined’: All the range types combined and padding applied

This allows Overlay plots to obtain each range and combine them appropriately for all the objects in the overlay.

If lims_as_soft_ranges is set to True, the xlim and ylim will be treated as soft ranges instead of the default case as hard ranges while computing the extents. This is used e.g. when apply_hard_bounds is True and xlim/ylim is set, in which case we limit the initial viewable range to xlim/ylim, but allow navigation up to the abs max between the data range and xlim/ylim.

get_padding(obj, extents)[source]#: Computes padding along the axes taking into account the plot aspect.

get_zorder(overlay, key, el)[source]#: Computes the z-order of element in the NdOverlay taking into account possible batching of elements.

init_artists(ax, plot_args, plot_kwargs)[source]#: Initializes the artist based on the plot method declared on the plot.

refresh(**kwargs)[source]#: Refreshes the plot by rerendering it and then pushing the updated data if the plot has an associated Comm.

set_root(root)[source]#: Sets the root model on all subplots.

property state#: The plotting state that gets updated via the update method and used by the renderer to generate output.

teardown_handles()[source]#: If no custom update_handles method is supplied this method is called to tear down any previous handles before replacing them.

traverse(fn=None, specs=None, full_breadth=True)[source]#: Traverses any nested DimensionedPlot returning a list of all plots that match the specs. The specs should be supplied as a list of either Plot types or callables, which should return a boolean given the plot class.

class holoviews.plotting.mpl.chart.SpreadPlot(element, **params)[source]#

Bases: AreaPlot

Parameters inherited from:

padding = param.ClassSelector(allow_refs=False, class_=(<class ‘int’>, <class ‘float’>, <class ‘tuple’>), default=(0, 0.1), label=’Padding’, nested_refs=False, rx=<param.reactive.reactive_ops object at 0x1788b2d50>): Fraction by which to increase auto-ranged extents to make datapoints more visible around borders. To compute padding, the axis whose screen size is largest is chosen, and the range of that axis is increased by the specified fraction along each axis. Other axes are then padded ensuring that the amount of screen space devoted to padding is equal for all axes. If specified as a tuple, the int or float values in the tuple will be used for padding in each axis, in order (x,y or x,y,z). For example, for padding=0.2 on a 800x800-pixel plot, an x-axis with the range [0,10] will be padded by 20% to be [-1,11], while a y-axis with a range [0,1000] will be padded to be [-100,1100], which should make the padding be approximately the same number of pixels. But if the same plot is changed to have a height of only 200, the y-range will then be [-400,1400] so that the y-axis padding will still match that of the x-axis. It is also possible to declare non-equal padding value for the lower and upper bound of an axis by supplying nested tuples, e.g. padding=(0.1, (0, 0.1)) will pad the x-axis lower and upper bound as well as the y-axis upper bound by a fraction of 0.1 while the y-axis lower bound is not padded at all.
show_legend = param.Boolean(allow_refs=False, default=False, label=’Show legend’, nested_refs=False, rx=<param.reactive.reactive_ops object at 0x1788c4450>): Whether to show legend for the plot.

class holoviews.plotting.mpl.chart.VectorFieldPlot(*args, **kwargs)[source]#

Bases: ColorbarPlot

Renders vector fields in sheet coordinates. The vectors are expressed in polar coordinates and may be displayed according to angle alone (with some common, arbitrary arrow length) or may be true polar vectors.

The color or magnitude can be mapped onto any dimension using the color_index and size_index.

The length of the arrows is controlled by the ‘scale’ style option. The scaling of the arrows may also be controlled via the normalize_lengths and rescale_lengths plot option, which will normalize the lengths to a maximum of 1 and scale them according to the minimum distance respectively.

Parameters inherited from:

padding = param.ClassSelector(allow_refs=False, class_=(<class ‘int’>, <class ‘float’>, <class ‘tuple’>), default=0.05, label=’Padding’, nested_refs=False, rx=<param.reactive.reactive_ops object at 0x17891c250>): Fraction by which to increase auto-ranged extents to make datapoints more visible around borders.

Magnitude is expected to be scaled between 0-1, by default the magnitudes are rescaled relative to the minimum distance between vectors, this can be disabled with the rescale_lengths option.

Valid values are ‘surface’, ‘wireframe’ and ‘contour’.

anim(start=0, stop=None, fps=30)[source]#: Method to return a matplotlib animation. The start and stop frames may be specified as well as the fps.

cleanup()[source]#: Cleans up references to the plot on the attached Stream subscribers.

compute_ranges(obj, key, ranges)[source]#: Given an object, a specific key, and the normalization options, this method will find the specified normalization options on the appropriate OptionTree, group the elements according to the selected normalization option (i.e. either per frame or over the whole animation) and finally compute the dimension ranges in each group. The new set of ranges is returned.

get_aspect(xspan, yspan)[source]#: Computes the aspect ratio of the plot

get_extents(element, ranges, range_type='combined', dimension=None, xdim=None, ydim=None, zdim=None, lims_as_soft_ranges=False, **kwargs)[source]#

Gets the extents for the axes from the current Element. The globally computed ranges can optionally override the extents.

The extents are computed by combining the data ranges, extents and dimension ranges. Each of these can be obtained individually by setting the range_type to one of:

This allows Overlay plots to obtain each range and combine them appropriately for all the objects in the overlay.

If lims_as_soft_ranges is set to True, the xlim and ylim will be treated as soft ranges instead of the default case as hard ranges while computing the extents. This is used e.g. when apply_hard_bounds is True and xlim/ylim is set, in which case we limit the initial viewable range to xlim/ylim, but allow navigation up to the abs max between the data range and xlim/ylim.

If n is greater than the number of available frames, update using the last available frame.

update_handles(key, axis, element, ranges, style)[source]#: Update the elements of the plot.

class holoviews.plotting.mpl.element.OverlayPlot(overlay, ranges=None, **params)[source]#

Bases: LegendPlot, GenericOverlayPlot

OverlayPlot supports compositors processing of Overlays across maps.

Parameters inherited from:

anim(start=0, stop=None, fps=30)[source]#: Method to return a matplotlib animation. The start and stop frames may be specified as well as the fps.

cleanup()[source]#: Cleans up references to the plot on the attached Stream subscribers.

compute_ranges(obj, key, ranges)[source]#: Given an object, a specific key, and the normalization options, this method will find the specified normalization options on the appropriate OptionTree, group the elements according to the selected normalization option (i.e. either per frame or over the whole animation) and finally compute the dimension ranges in each group. The new set of ranges is returned.

get_aspect(xspan, yspan)[source]#: Computes the aspect ratio of the plot

get_extents(overlay, ranges, range_type='combined', dimension=None, **kwargs)[source]#

Gets the extents for the axes from the current Element. The globally computed ranges can optionally override the extents.

The extents are computed by combining the data ranges, extents and dimension ranges. Each of these can be obtained individually by setting the range_type to one of:

‘data’: Just the data ranges
‘extents’: Element.extents
‘soft’: Dimension.soft_range values
‘hard’: Dimension.range values

To obtain the combined range, which includes range padding the default may be used:

‘combined’: All the range types combined and padding applied

This allows Overlay plots to obtain each range and combine them appropriately for all the objects in the overlay.

If lims_as_soft_ranges is set to True, the xlim and ylim will be treated as soft ranges instead of the default case as hard ranges while computing the extents. This is used e.g. when apply_hard_bounds is True and xlim/ylim is set, in which case we limit the initial viewable range to xlim/ylim, but allow navigation up to the abs max between the data range and xlim/ylim.

`heatmap` Module#

class holoviews.plotting.mpl.heatmap.HeatMapPlot(*args, **kwargs)[source]#

Bases: HeatMapMixin, QuadMeshPlot

Parameters inherited from:

padding = param.ClassSelector(allow_refs=False, class_=(<class ‘int’>, <class ‘float’>, <class ‘tuple’>), default=0, label=’Padding’, nested_refs=False, rx=<param.reactive.reactive_ops object at 0x179c8da10>): Fraction by which to increase auto-ranged extents to make datapoints more visible around borders. To compute padding, the axis whose screen size is largest is chosen, and the range of that axis is increased by the specified fraction along each axis. Other axes are then padded ensuring that the amount of screen space devoted to padding is equal for all axes. If specified as a tuple, the int or float values in the tuple will be used for padding in each axis, in order (x,y or x,y,z). For example, for padding=0.2 on a 800x800-pixel plot, an x-axis with the range [0,10] will be padded by 20% to be [-1,11], while a y-axis with a range [0,1000] will be padded to be [-100,1100], which should make the padding be approximately the same number of pixels. But if the same plot is changed to have a height of only 200, the y-range will then be [-400,1400] so that the y-axis padding will still match that of the x-axis. It is also possible to declare non-equal padding value for the lower and upper bound of an axis by supplying nested tuples, e.g. padding=(0.1, (0, 0.1)) will pad the x-axis lower and upper bound as well as the y-axis upper bound by a fraction of 0.1 while the y-axis lower bound is not padded at all.
xticks = param.Parameter(allow_refs=False, default=20, label=’Xticks’, nested_refs=False, rx=<param.reactive.reactive_ops object at 0x179c8f0d0>): Ticks along x-axis/segments specified as an integer, explicit list of ticks or function. If None, no ticks are shown.

The min, max or NaN color may specify an RGB(A) color as a color hex string of the form #FFFFFF or #FFFFFFFF or a length 3 or length 4 tuple specifying values in the range 0-1 or a named HTML color.
radial = param.Boolean(allow_refs=False, default=False, label=’Radial’, nested_refs=False, rx=<param.reactive.reactive_ops object at 0x179c8d450>): Whether the HeatMap should be radial

get_aspect(xspan, yspan)[source]#: Computes the aspect ratio of the plot

get_extents(view, ranges, range_type='combined', **kwargs)[source]#

Gets the extents for the axes from the current Element. The globally computed ranges can optionally override the extents.

The extents are computed by combining the data ranges, extents and dimension ranges. Each of these can be obtained individually by setting the range_type to one of:

‘data’: Just the data ranges
‘extents’: Element.extents
‘soft’: Dimension.soft_range values
‘hard’: Dimension.range values

To obtain the combined range, which includes range padding the default may be used:

‘combined’: All the range types combined and padding applied

This allows Overlay plots to obtain each range and combine them appropriately for all the objects in the overlay.

If lims_as_soft_ranges is set to True, the xlim and ylim will be treated as soft ranges instead of the default case as hard ranges while computing the extents. This is used e.g. when apply_hard_bounds is True and xlim/ylim is set, in which case we limit the initial viewable range to xlim/ylim, but allow navigation up to the abs max between the data range and xlim/ylim.

class holoviews.plotting.mpl.raster.QuadMeshPlot(*args, **kwargs)[source]#

Bases: ColorbarPlot

Parameters inherited from:

padding = param.ClassSelector(allow_refs=False, class_=(<class ‘int’>, <class ‘float’>, <class ‘tuple’>), default=0, label=’Padding’, nested_refs=False, rx=<param.reactive.reactive_ops object at 0x17a57c290>): Fraction by which to increase auto-ranged extents to make datapoints more visible around borders. To compute padding, the axis whose screen size is largest is chosen, and the range of that axis is increased by the specified fraction along each axis. Other axes are then padded ensuring that the amount of screen space devoted to padding is equal for all axes. If specified as a tuple, the int or float values in the tuple will be used for padding in each axis, in order (x,y or x,y,z). For example, for padding=0.2 on a 800x800-pixel plot, an x-axis with the range [0,10] will be padded by 20% to be [-1,11], while a y-axis with a range [0,1000] will be padded to be [-100,1100], which should make the padding be approximately the same number of pixels. But if the same plot is changed to have a height of only 200, the y-range will then be [-400,1400] so that the y-axis padding will still match that of the x-axis. It is also possible to declare non-equal padding value for the lower and upper bound of an axis by supplying nested tuples, e.g. padding=(0.1, (0, 0.1)) will pad the x-axis lower and upper bound as well as the y-axis upper bound by a fraction of 0.1 while the y-axis lower bound is not padded at all.
show_legend = param.Boolean(allow_refs=False, default=False, label=’Show legend’, nested_refs=False, rx=<param.reactive.reactive_ops object at 0x17a57d910>): Whether to show legend for the plot.

The min, max or NaN color may specify an RGB(A) color as a color hex string of the form #FFFFFF or #FFFFFFFF or a length 3 or length 4 tuple specifying values in the range 0-1 or a named HTML color.
nodata = param.Integer(allow_None=True, allow_refs=False, inclusive_bounds=(True, True), label=’Nodata’, nested_refs=False, rx=<param.reactive.reactive_ops object at 0x17a57dd10>): Optional missing-data value for integer data.

cleanup()[source]#: Cleans up references to the plot on the attached Stream subscribers.

compute_ranges(obj, key, ranges)[source]#: Given an object, a specific key, and the normalization options, this method will find the specified normalization options on the appropriate OptionTree, group the elements according to the selected normalization option (i.e. either per frame or over the whole animation) and finally compute the dimension ranges in each group. The new set of ranges is returned.

get_extents(element, ranges, range_type='combined', dimension=None, xdim=None, ydim=None, zdim=None, lims_as_soft_ranges=False, **kwargs)[source]#

Gets the extents for the axes from the current Element. The globally computed ranges can optionally override the extents.

The extents are computed by combining the data ranges, extents and dimension ranges. Each of these can be obtained individually by setting the range_type to one of:

‘data’: Just the data ranges
‘extents’: Element.extents
‘soft’: Dimension.soft_range values
‘hard’: Dimension.range values

To obtain the combined range, which includes range padding the default may be used:

‘combined’: All the range types combined and padding applied

This allows Overlay plots to obtain each range and combine them appropriately for all the objects in the overlay.

If lims_as_soft_ranges is set to True, the xlim and ylim will be treated as soft ranges instead of the default case as hard ranges while computing the extents. This is used e.g. when apply_hard_bounds is True and xlim/ylim is set, in which case we limit the initial viewable range to xlim/ylim, but allow navigation up to the abs max between the data range and xlim/ylim.

get_padding(obj, extents)[source]#: Computes padding along the axes taking into account the plot aspect.

To compute padding, the axis whose screen size is largest is chosen, and the range of that axis is increased by the specified fraction along each axis. Other axes are then padded ensuring that the amount of screen space devoted to padding is equal for all axes. If specified as a tuple, the int or float values in the tuple will be used for padding in each axis, in order (x,y or x,y,z). For example, for padding=0.2 on a 800x800-pixel plot, an x-axis with the range [0,10] will be padded by 20% to be [-1,11], while a y-axis with a range [0,1000] will be padded to be [-100,1100], which should make the padding be approximately the same number of pixels. But if the same plot is changed to have a height of only 200, the y-range will then be [-400,1400] so that the y-axis padding will still match that of the x-axis. It is also possible to declare non-equal padding value for the lower and upper bound of an axis by supplying nested tuples, e.g. padding=(0.1, (0, 0.1)) will pad the x-axis lower and upper bound as well as the y-axis upper bound by a fraction of 0.1 while the y-axis lower bound is not padded at all.

cleanup()[source]#: Cleans up references to the plot on the attached Stream subscribers.

compute_ranges(obj, key, ranges)[source]#: Given an object, a specific key, and the normalization options, this method will find the specified normalization options on the appropriate OptionTree, group the elements according to the selected normalization option (i.e. either per frame or over the whole animation) and finally compute the dimension ranges in each group. The new set of ranges is returned.

get_aspect(xspan, yspan)[source]#: Computes the aspect ratio of the plot

get_extents(element, ranges, range_type='combined', **kwargs)[source]#

Gets the extents for the axes from the current Element. The globally computed ranges can optionally override the extents.

The extents are computed by combining the data ranges, extents and dimension ranges. Each of these can be obtained individually by setting the range_type to one of:

‘data’: Just the data ranges
‘extents’: Element.extents
‘soft’: Dimension.soft_range values
‘hard’: Dimension.range values

To obtain the combined range, which includes range padding the default may be used:

‘combined’: All the range types combined and padding applied

This allows Overlay plots to obtain each range and combine them appropriately for all the objects in the overlay.

If lims_as_soft_ranges is set to True, the xlim and ylim will be treated as soft ranges instead of the default case as hard ranges while computing the extents. This is used e.g. when apply_hard_bounds is True and xlim/ylim is set, in which case we limit the initial viewable range to xlim/ylim, but allow navigation up to the abs max between the data range and xlim/ylim.

get_padding(obj, extents)[source]#: Computes padding along the axes taking into account the plot aspect.

get_zorder(overlay, key, el)[source]#: Computes the z-order of element in the NdOverlay taking into account possible batching of elements.

initialize_plot(*args, **kwargs)[source]#: Initialize the matplotlib figure.

matches(spec)[source]#: Matches a specification against the current Plot.

refresh(**kwargs)[source]#: Refreshes the plot by rerendering it and then pushing the updated data if the plot has an associated Comm.

set_root(root)[source]#: Sets the root model on all subplots.

property state#: The plotting state that gets updated via the update method and used by the renderer to generate output.

teardown_handles()[source]#: If no custom update_handles method is supplied this method is called to tear down any previous handles before replacing them.

traverse(fn=None, specs=None, full_breadth=True)[source]#: Traverses any nested DimensionedPlot returning a list of all plots that match the specs. The specs should be supplied as a list of either Plot types or callables, which should return a boolean given the plot class.

update(key)[source]#: Update the internal state of the Plot to represent the given key tuple (where integers represent frames). Returns this state.

update_frame(*args, **kwargs)[source]#

Set the plot(s) to the given frame number. Operates by manipulating the matplotlib objects held in the self._handles dictionary.

If n is greater than the number of available frames, update using the last available frame.

update_handles(key, axis, element, ranges, style)[source]#: Update the elements of the plot.

class holoviews.plotting.mpl.raster.RasterGridPlot(layout, keys=None, dimensions=None, create_axes=False, ranges=None, layout_num=1, **params)[source]#

Bases: GridPlot, OverlayPlot

RasterGridPlot evenly spaces out plots of individual projections on a grid, even when they differ in size. Since this class uses a single axis to generate all the individual plots it is much faster than the equivalent using subplots.

get_extents(view, ranges, range_type='combined', **kwargs)[source]#

Gets the extents for the axes from the current Element. The globally computed ranges can optionally override the extents.

By default simply attaches the plot to bokeh’s curdoc and returns the Document, if show option is supplied creates an Application instance and displays it either in a browser window or inline if notebook extension has been loaded. Using the new_window option the app may be displayed in a new browser tab once the notebook extension has been loaded. A websocket origin is required when launching from an existing tornado server (such as the notebook) and it is not on the default port (‘localhost:8888’).

classmethod load_nb(inline=True)[source]#: Initialize matplotlib backend

classmethod plot_options(obj, percent_size)[source]#

Given a holoviews object and a percentage size, apply heuristics to compute a suitable figure size. For instance, scaling layouts and grids linearly can result in unwieldy figure sizes when there are a large number of elements. As ad hoc heuristics are used, this functionality is kept separate from the plotting classes themselves.

Used by the IPython Notebook display hooks and the save utility. Note that this can be overridden explicitly per object using the fig_size and size plot options.

classmethod plotting_class(obj)[source]#: Given an object or Element class, return the suitable plotting class needed to render it with the current renderer.

teardown_handles()[source]#: If no custom update_handles method is supplied this method is called to tear down any previous handles before replacing them.

traverse(fn=None, specs=None, full_breadth=True)[source]#: Traverses any nested DimensionedPlot returning a list of all plots that match the specs. The specs should be supplied as a list of either Plot types or callables, which should return a boolean given the plot class.

update(key)[source]#: Update the internal state of the Plot to represent the given key tuple (where integers represent frames). Returns this state.

update_frame(*args, **kwargs)[source]#

Set the plot(s) to the given frame number. Operates by manipulating the matplotlib objects held in the self._handles dictionary.

If n is greater than the number of available frames, update using the last available frame.

update_handles(key, axes, element, ranges, style)[source]#: Update the elements of the plot.

`util` Module#

class holoviews.plotting.mpl.util.CFTimeConverter(*, interval_multiples=True)[source]#

Bases: DateConverter

Defines conversions for cftime types by extending nc_time_axis.

axisinfo(unit, axis)[source]#

Return the ~matplotlib.units.AxisInfo for unit.

unit is a ~datetime.tzinfo instance or None. The axis argument is required but not used.

classmethod convert(value, unit, axis)[source]#

If value is not already a number or sequence of numbers, convert it with date2num.

The unit and axis arguments are not used.

static default_units(x, axis)[source]#: Return the ~datetime.tzinfo instance of x or of its first element, or None

class holoviews.plotting.mpl.util.EqHistNormalize(vmin=None, vmax=None, clip=False, rescale_discrete_levels=True, nbins=65536, ncolors=256)[source]#

Bases: Normalize

autoscale(A)[source]#: Set vmin, vmax to min, max of A.

autoscale_None(A)[source]#: If vmin or vmax are not set, use the min/max of A to set them.

inverse(value)[source]#

Maps the normalized value (i.e., index in the colormap) back to image data value.

Parameters#

value: Normalized value.

process_value(data)[source]#

Homogenize the input value for easy and efficient normalization.

value can be a scalar or sequence.

Parameters#

value: Data to normalize.

Returns#

resultmasked array: Masked array with the same shape as value.
is_scalarbool: Whether value is a scalar.

Notes#

Float dtypes are preserved; integer types with two bytes or smaller are converted to np.float32, and larger types are converted to np.float64. Preserving float32 when possible, and using in-place operations, greatly improves speed for large arrays.

scaled()[source]#: Return whether vmin and vmax are both set.

holoviews.plotting.mpl.util.axis_overlap(ax1, ax2)[source]#: Tests whether two axes overlap vertically

holoviews.plotting.mpl.util.filter_styles(style, group, other_groups, blacklist=None)[source]#

Filters styles which are specific to a particular artist, e.g. for a GraphPlot this will filter options specific to the nodes and edges.

Arguments#

style: dict: Dictionary of styles and values
group: str: Group within the styles to filter for
other_groups: list: Other groups to filter out
blacklist: list (optional): List of options to filter out

Returns#

filtered: dict: Filtered dictionary of styles

holoviews.plotting.mpl.util.fix_aspect(fig, nrows, ncols, title=None, extra_artists=None, vspace=0.2, hspace=0.2)[source]#: Calculate heights and widths of axes and adjust the size of the figure to match the aspect.

holoviews.plotting.mpl.util.get_raster_array(image)[source]#: Return the array data from any Raster or Image type

holoviews.plotting.mpl.util.get_tight_bbox(fig, bbox_extra_artists=None, pad=None)[source]#: Compute a tight bounding box around all the artists in the figure.

holoviews.plotting.mpl.util.is_color(color)[source]#: Checks if supplied object is a valid color spec.

holoviews.plotting.mpl.util.polygons_to_path_patches(element)[source]#: Converts Polygons into list of lists of matplotlib.patches.PathPatch objects including any specified holes. Each list represents one (multi-)polygon.

holoviews.plotting.mpl.util.resolve_rows(rows)[source]#: Recursively iterate over lists of axes merging them by their vertical overlap leaving a list of rows.

holoviews.plotting.mpl.util.ring_coding(array)[source]#: Produces matplotlib Path codes for exterior and interior rings of a polygon geometry.

holoviews.plotting.mpl.util.validate(style, value, vectorized=True)[source]#

Validates a style and associated value.

Arguments#

style: str: The style to validate (e.g. ‘color’, ‘size’ or ‘marker’)
value:: The style value to validate
vectorized: bool: Whether validator should allow vectorized setting

Returns#

valid: boolean or None: If validation is supported returns boolean, otherwise None

holoviews.plotting.mpl.util.wrap_formatter(formatter)[source]#: Wraps formatting function or string in appropriate matplotlib formatter type.

linestyle	description
`'-'` or `'solid'`	solid line
`'--'` or `'dashed'`	dashed line
`'-.'` or `'dashdot'`	dash-dotted line
`':'` or `'dotted'`	dotted line
`'none'`, `'None'`, `' '`, or `''`	draw nothing
