What does >>> matplotlib.get_backend() report? According to http://www.wingware.com/doc/howtos/matplotlib they are assuming TkAgg. You may also want to read the suggestions at http://matplotlib.sourceforge.net/users/shell.html for advice on how to use matplotlib interactively from the command shell in an IDE. Basically, you need to make sure your "backend" corresponds to the GUI and interactive mode is set to True.
