if you have already created the tk gui window and shown it, just call fig.canvas.draw() on each update of the vertices > 2. This is pretty fast.

The animated property has to be on the patch itself, so when you create the path patch, you would do patch = patches.PatchPath(path, animated=True) ax.add_patch(patch) JDH ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
