Me and my team are almost to the finishing point. Our final problem is
getting the graph to update.
When we run the graph the get the following issue: "
Traceback (most recent call last):
File "/home/gnelson/scc08whole/branch/realistic2d/gtkgui.py", line 100, in
update
self.ax.draw_artist(plt.contourf)
File "/usr/lib/python2.5/site-packages/matplotlib/axes.py", line 1535, in
draw_artist
a.draw(self._cachedRenderer)
AttributeError: 'function' object has no attribute 'draw'"
Our Code is at: " http://code.google.com/p/scc08/ "
and we are using the gtkgui.py
