I install matplotlib but, Paraview cannot find matplotlib 2.6.1.  
Matplotlib exist in the similar path as numpy.

```auto
/app/lib/python3.8/site-packages/matplotlib

```

Are there compile flags or settings I can make Paraview find matplotlib?

Thanks.

You need to enable `VTK_MODULE_ENABLE_VTK_RenderingMatplotlib` cmake option.

Edit: incorrect, see below.

enabling the module should not affect if ParaView reports matplotlib is found. Try calling `import matplotlib` in the Python shell in ParaView or `pvpython`. I suspect it’s failing.

Thank you. It is missing pyparsing.

Also if you don’t mind, could you give some comments on my Flatpak for Paraview?
