You have to set which GUI you want to use with the backend parameter
in the matplotlibrc configuration file. Typically, people put a copy
of this in their HOME dir. If you want to use WX, I suggest setting
backend : WXAgg
in your rc file.
You can obtain a default copy of the rc file at
http://matplotlib.sf.net/.matplotlibrc or in the matplotlib src
distribution.
