Associate point data to a simple cube mesh and show that the active scalars in the point array are the most recently added array.

>>> import pyvista as pv
>>> import numpy as np
>>> mesh = pv.Cube()
>>> mesh.point_data['data0'] = np.arange(mesh.n_points)
>>> mesh.point_data.active_scalars
pyvista_ndarray([0, 1, 2, 3, 4, 5, 6, 7])
