Good, than I would say that is a clear sign that you have a non interactive
backend.
Can you please give use the output of plt.get_backend() ?

This link http://matplotlib.org/faq/usage_faq.html#what-is-a-backend should
explain you what a backend is.
If you want to use always a specific backend, you should select it in the
matplotlibrc file
You should have a line like this
#backend : TkAgg
Just uncomment it and put the backend that you want to use

That is not surprising: if matplotlib doesn't use an interactive backend,
you can't show the figures, whatever interpreter you use.
I hope that now is clearer,
