[Matplotlib-users] plot3D in subplot

[Bing <bin...@gm...>]

Hello,
   Could anyone tell me how to use plot3D in a subplot?
I looked at the examples at
  http://www.scipy.org/Cookbook/Matplotlib/mplot3D
But seems to me that matplotlib.axes3d.Axes3D can
be only constructed from a Figure instance but
not from a Subplot instance.

Thanks,
Bing
