Good catch Perry. You need
Thank you both very much. That did the trick. I put a hold on the figure
and then a hold(False) on the one axis for which I wanted it and all
works well now.

Thanks. That was helpful -- though also a bit confusing, in that I'm
using the TkAgg back end and calling pylab.draw() doesn't update
anything visible on my FigureCanvasAgg object. (As an aside, calling
show() on my FigureCanvasAgg object seems to work -- the code originally
did that when I got it -- but the manual and FAQ clearly point to using

All the class docs can be found at

That's what I was really missing. Thanks! Now that I know about it, I'm
