Hmm, could you explain why you want to avoid the wx mainloop,
and what you mean by this. Do want wx to process events, right?

You say you're trying to embed matplotlib on WX, but the code
you posted doesn't do this.  It uses pylab, which creates a wx
App and runs its mainloop when you do show().  My guess is that
you're probably start getting the behavior you expect once that
auto-created wxapp is killed.

A simple answer would be to not use pylab, and just use a
matplotlib FigureCanvas with wx.  You'd have a mainloop then (I
don't see how you avoid that!!). You could start another thread
for non-GUI processing if you wanted, or *use* the mainloop's
events (timers or data-changing events) to update the plot.

Hope that helps,
