The pyplot/pylab APIs are intended for scripting and interactive use,
like in ipython. They are not meant for integration with a gui
application running its own event loop. See
http://matplotlib.sourceforge.net/examples/user_interfaces/embedding_in_qt4.html
for an example of how to use matplotlib in a PyQt4 applitcation.
