holoviews.plotting.mpl.util module#
- class holoviews.plotting.mpl.util.CFTimeConverter(*, interval_multiples=True)[source]#
Bases:
DateConverterDefines conversions for cftime types by extending nc_time_axis.
- class holoviews.plotting.mpl.util.EqHistNormalize(vmin=None, vmax=None, clip=False, rescale_discrete_levels=True, nbins=65536, ncolors=256)[source]#
Bases:
Normalize- 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.
- 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.
Parameters#
- styledict
Dictionary of styles and values
- groupstr
Group within the styles to filter for
- other_groupslist
Other groups to filter out
- blacklistlist, optional
List of options to filter out
Returns#
- filtereddict
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.
Parameters#
- stylestr
The style to validate (e.g. ‘color’, ‘size’ or ‘marker’)
- value :
The style value to validate
- vectorizedbool
Whether validator should allow vectorized setting
Returns#
- validboolean or None
If validation is supported returns boolean, otherwise None
