Well, you could explicitly provide the color to "plot" but this is
masking a deeper problem.  You do not want to e callng "plot" on every
window redraw event.  If you post a code snippet, we might be able to
help.

The font problem turned out to be simply that I didn't realize that the
latest version of matplotlib comes with the matplotlibrc file commented out
(I had not tried to change fonts before so hadn't noticed I couldn't).
Uncommented the fonts section solved it.  Thanks for the tip.

Is there a way to disable color cycling?
