ColorListSelectionDisplay(color_prop='color', alpha_prop='alpha', backend=None)¶
Selection display class for elements that support coloring by a vectorized color list.
Selection display class that returns input element unchanged. For use with elements that don’t support displaying selections.
OverlaySelectionDisplay(color_prop='color', is_cmap=False, supports_region=True)¶
Selection display base class that represents selections by overlaying colored subsets on top of the original element in an Overlay container.
Base class for selection display classes. Selection display classes are responsible for transforming an element (or DynamicMap that produces an element) into a HoloViews object that represents the current selection state.
Operation which automatically links selections between elements in the supplied HoloViews object. Can be used a single time or be used as an instance to apply the linked selections across multiple objects.
Parameters inherited from:
holoviews.selection._base_link_selections: link_inputs, show_regions
cross_filter_mode= param.Selector(default=’intersect’, objects=[‘overwrite’, ‘intersect’])
Determines how to combine selections across different elements.
index_cols= param.List(bounds=(0, None))
If provided, selection switches to index mode where all queries are expressed solely in terms of discrete values along the index_cols. All Elements given to link_selections must define the index_cols, either as explicit dimensions or by sharing an underlying Dataset that defines them.
dim expression of the current selection or None to indicate that everything is selected.
Color of selected data, or None to use the original color of each element.
selection_mode= param.Selector(default=’overwrite’, objects=[‘overwrite’, ‘intersect’, ‘union’, ‘inverse’])
Determines how to combine successive selections on the same element.
unselected_alpha= param.Magnitude(bounds=(0.0, 1.0), default=0.1, inclusive_bounds=(True, True))
Alpha of unselected data.
Color of unselected data.

Same as Parameterized.script_repr, except that X.classname(Y is replaced with X.classname.instance(Y
The datashader colormap for selected data
Returns a parameter which reflects the current selection when applied to the supplied data, making it easy to create a callback which depends on the current selection.
data: A Dataset type or data which can be cast to a Dataset
A parameter which reflects the current selection
