LegendItem#

LegendItem(graphic[, label, ...])

The legend representation of a graphic, created with Graphic.create_legend_item().

`LegendItem.cmap_transform_labels`	get or set the label of each cmap_transform value of a qualitative colormap
`LegendItem.colorbar`	the colorbar of this item, set when the graphic uses a quantitative colormap
`LegendItem.elements`	the elements of this item, empty when it is shown as a colorbar
`LegendItem.figure`	the figure this container is drawn in
`LegendItem.graphic`	the graphic this item represents
`LegendItem.label`	get or set the label of this item, the graphic's name is used if it is not set
`LegendItem.legend`	the legend this item has been added to

`LegendItem.check_graphic_mode`()	Make the item again if the graphic switched between uniform colors, per-vertex colors and a colormap, which replaces the feature instance and clears its handlers, so there is no event to follow.
`LegendItem.draw`()	pushes and pops the ID to keep identical containers unique within one frame
`LegendItem.update`()	Implement your GUI here and it will be drawn within the host window
