Hello, I'm not familiar with the draw_artist functionality, but for me there seems to to be the following replacement needed (due to a typo):
self.ax.draw_artist(plt.contourf) -> self.ax.draw_artist(self.contour) because otherwise you are trying to draw a matplotlib function, which seems to be not reasonable and explains the error, because this function has no attribute 'draw'. Good luck. best regards Matthias On Tuesday 31 March 2009 01:45:28 Deltarodigy wrote: > Me and my team are almost to the finishing point.
