class holoviews.plotting.links.DataLink(source, target=None, **params)[source]#

Bases: Link

DataLink defines a link in the data between two objects allowing them to be selected together. In order for a DataLink to be established the source and target data must be of the same length.

Parameter Definitions

class holoviews.plotting.links.Link(source, target=None, **params)[source]#

Bases: Parameterized

A Link defines some connection between a source and target object in their visualization. It is quite similar to a Stream as it allows defining callbacks in response to some change or event on the source object, however, unlike a Stream, it does not transfer data and make it available to user defined subscribers. Instead a Link directly causes some action to occur on the target, for JS based backends this usually means that a corresponding JS callback will effect some change on the target in response to a change on the source.

A Link must define a source object which is what triggers events, but must not define a target. It is also possible to define bi- directional links between the source and target object.

Parameter Definitions

---

link()[source]#

Registers the Link

classmethod register_callback(backend, callback)[source]#

Register a LinkCallback providing the implementation for the Link for a particular backend.

unlink()[source]#

Unregisters the Link

class holoviews.plotting.links.RangeToolLink(source, target=None, **params)[source]#

Bases: Link

The RangeToolLink sets up a link between a RangeTool on the source plot and the axes on the target plot. It is useful for exploring a subset of a larger dataset in more detail. By default it will link along the x-axis but using the axes parameter both axes may be linked to the tool.

Example of how to use RangeToolLink can be found here: https ://www.holoviews.org/gallery/demos/bokeh/timeseries_range_tool.html

Parameter Definitions

---

axes = ListSelector(default=['x'], label='Axes', names={}, objects=['x', 'y'])

Which axes to link the tool to.

boundsx = Tuple(allow_None=True, label='Boundsx', length=2)

(start, end) bounds for the x-axis

boundsy = Tuple(allow_None=True, label='Boundsy', length=2)

(start, end) bounds for the y-axis

intervalsx = Tuple(allow_None=True, label='Intervalsx', length=2)

(min, max) intervals for the x-axis

intervalsy = Tuple(allow_None=True, label='Intervalsy', length=2)

(min, max) intervals for the y-axis

use_handles = Boolean(default=True, label='Use handles')

Whether to display handles. Only available from Bokeh 3.5 onwards.

start_gesture = Selector(default='tap', label='Start gesture', names={}, objects=['pan', 'tap', 'none'])

Gesture to start a range selection. Only available from Bokeh 3.5 onwards.

inverted = Boolean(default=True, label='Inverted')

Whether to invert the highlighting of the range selection. Only available from Bokeh 3.5 onwards.

class holoviews.plotting.links.RectanglesTableLink(source, target=None, **params)[source]#

Bases: Link

Links a Rectangles element to a Table.

Parameter Definitions

class holoviews.plotting.links.SelectionLink(source, target=None, **params)[source]#

Bases: Link

Links the selection between two glyph renderers.

Parameter Definitions

class holoviews.plotting.links.VertexTableLink(source, target, **params)[source]#

Bases: Link

Defines a Link between a Path type and a Table that will display the vertices of selected path.

Parameter Definitions

vertex_columns = List(bounds=(0, None), default=[], label='Vertex columns')
