property _BaseMapper.lookup_table: LookupTable

Return or set the lookup table.

Examples

Return the lookup table of a dataset mapper.

>>> import pyvista as pv
>>> mesh = pv.Sphere()
>>> pl = pv.Plotter()
>>> actor = pl.add_mesh(
...     mesh, scalars=mesh.points[:, 2], cmap='bwr'
... )
>>> actor.mapper.lookup_table
LookupTable (...)
  Table Range:                (-0.5, 0.5)
  N Values:                   256
  Above Range Color:          None
  Below Range Color:          None

Return the lookup table of a composite dataset mapper.

>>> 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.lookup_table
