pyvista.CompositePolyDataMapper.set_unique_colors

CompositePolyDataMapper.set_unique_colors(color_cycler: bool = True)

Set each block of the dataset to a unique color.

This uses matplotlib’s color cycler by default.

When a custom color cycler, or a sequence of color-like objects, is passed it sets the blocks to the corresponding colors.

Parameters:

color_cyclerbool | str | cycler.Cycler | sequence[ColorLike]

The sequence of colors to cycle through, if True, uses matplotlib cycler.

Examples

Set each block of the composite dataset to a unique color.

>>> import pyvista as pv
>>> dataset = pv.MultiBlock(
...     [pv.Cube(), pv.Sphere(center=(0, 0, 1))]
... )
>>> pl = pv.Plotter()
>>> actor, mapper = pl.add_composite(dataset)
>>> mapper.set_unique_colors()
>>> mapper.block_attr[1].color
Color(name='tab:orange', hex='#ff7f0eff', opacity=255)
>>> mapper.block_attr[2].color
Color(name='tab:green', hex='#2ca02cff', opacity=255)
