Colour-keying works in Blender -- I only need to tweak all those parameters
a bit more to get a satisfying end result.

Case closed and it was not a Python/Matplotlib issue.

I still need the animated numerical thing but drop it here. I will be
back with a separate thread/subject for that.

Again, thanks for the input.
