Patch3DCollection.set_data

Thanks Reinier,
   For posterity ended up just doing the following:

matplotlib.interactive(True)
...
s = ax.scatter(data1, data2, data3)
draw()
s.remove()
s = ax.scatter(data4, data5, data6)
draw()

···

Hi Ryan,

This is currently not supported. Since also the 2D PatchCollection does not support it I >don't see how to easily add it either...

Cheers,
Reinier
