[Paraview] Import a four-dimensional array and "slice" one dimension to plot in 3D

[Frederic Perez]

Thank you for this suggestion.

I have been looking at programmable sources, and although they are new
to me, I think I have found a few issues for my objective:
- I seem unable to import a few python packages that I know I can
import in a usual python command.
- I can't find a way to have this programmable source saved as a file,
so that other people can use it.
- If people want to have more flexibility using my programmable
source, they need to get their hands in the code, which is precisely
what I am trying to avoid.

Are there solutions to these issues? Or should I simply go make a
plugin, instead of a programmable source?

Cheers
Fred
