[Matplotlib-users] redrawing plot with transparent background in wx

[Nat E. <nat...@gm...>]

I'm embedding a plot in a wxPython panel, and I'd like it to blend in as
much as possible, i.e. the area outside the plot itself should be
transparent.  I can call figure.figurePatch.set_alpha(0.0) to do this under
normal circumstances, but in this case I'm also trying to redraw the plot
periodically in response to a background process.  When I do this,
figure.clear() clears the plot area, but not the axes and labels, so I end
up with all of the old axes superimposed.  Is there a way to completely
erase the background before redrawing?

thanks,
Nat
