cache_full_map = Bool(True)

whether to pre-compute the full colormapped RGB(A) image

color_mapper = Property

Convenience property for value_mapper as color_mapper

fade_alpha = Float(0.3)

alpha value to use to fade out unselected data points when there is an active selection

fade_background = Tuple((0, 0, 0))

RGB color to use to fade out unselected points.

set_value_selection(val)
