The reason this does not work in separate cells is that a figure object
gets closed at the end of a ipython cell.  An ax object no longer works
when its parent figure is closed.  This is not limited to 3d plots.  I
would be surprised to see ax.plot() work if a non-3d axes object was made
in a different cell.
