I'm using 'axes.clear()' to clear the canvas and then I call
> plot_date. Is there a better way to clear the plots?
That is an alias for ax.cla, should work fine.

For some reason matplotlib is not finding its config file and is
falling back on the gtk backend, which is failing on your system.
Grab a copy of the rc file at http://matplotlib.sf.net/.matplotlibrc
and drop it in C:\Python24\share\matplotlib, and edit the backend
setting to a backend appropriate for your system, eg TkAgg or WXAgg.
