I think it is mostly an issue with how IPython interfaces with matplotlib.
If you were running from a pure python prompt, then I would suspect it to
work (haven't tried myself, though). Note that the --pylab option to
ipython is now highly discouraged. Instead, I would try the "%matplotlib
interactive" cell magic instead (I think that is the right incantation).
