If x,y don't change, and if you are not using masked arrays, then you
might be able to add something like this:
self.plots3.set_array(np.transpose(z).ravel())
self.plots3.autoscale()
self.figure.canvas.draw()
The colorbar range will be updated automatically.
If x,y do change, then just clear the figure and regenerate it with the
new data.
