Re: [Matplotlib-users] Python shell despite no IPython problems

[Ryan N. <rne...@gm...>]

Sorry Brenton, I meant for my reply to go to the entire list.

Anyway, in your response, I take it that you meant to say that the window
appears and disappears immediately. Yes?

What happens if you restart the Python interpreter and type the following?
>>> import matplotlib
>>> matplotlib.use('TkAgg')
>>> import matplotlib.pyplot as plt
>>> plt.plot([1,2,3])
>>> plt.show()
Does my first example work fine in the IPython interpreter? (Sorry, I'm not
on my Windows machine right now, so I can't tell you if I'm seeing the same
problem.)
