UniformGrid object has no attribute point_data

[RichardScottOZ]

Just running this example:-
https://docs.pyvista.org/examples/00-load/create-uniform-grid.html

To Reproduce

# Create the 3D NumPy array of spatially referenced data
# This is spatially referenced such that the grid is 20 by 5 by 10
#   (nx by ny by nz)
values = np.linspace(0, 10, 1000).reshape((20, 5, 10))
values.shape

# Create the spatial reference
grid2 = pv.UniformGrid()

# Set the grid dimensions: shape because we want to inject our values on the
#   POINT data
grid2.dimensions = values.shape

# Edit the spatial reference
grid2.origin = (100, 33, 55.6)  # The bottom left corner of the data set
grid2.spacing = (1, 5, 2)  # These are the cell sizes along each axis

# Add the data values to the cell data
grid2.point_data["values"] = values.flatten(order="F")  # Flatten the array!

# Now plot the grid!
grid2.plot(show_edges=True)

Just don't need the point_data part? So maybe not a bug - a doc update?

[RichardScottOZ]

Version issue?

[akaszynski]

Version issue?

Exactly. Upgrade to pyvista>=0.32.0 because we've updated the API to move from point_arrays --> point_data. The reasoning behind this is a bit complex, but for fun you can read https://docs.pyvista.org/user-guide/data_model.html.

BTW, nice specs!

Thanks.

Yes, been a crucial bit of gear the last 2 years!

[RichardScottOZ]

The data model overview is good.
