I have some (not much) experience with matplotlib, and have been
impressed by it.  I suspect that by itself matplotlib would be
inadequate to your task - I encountered Quantum Mechanics in
university and hated it, but that was ... decades ago, so I'm not
claiming to understand.  But it sounds like there are wrappers, and if
they're based on matplotlib I think they chose a good starting point.
Hope this helps, if only a little.
