You need to add the patch to the second axes.
patch = ConnectionPatch((.5, .5), (.7, .3), 'data', 'data',
axesA=ax1, axesB=ax2,
zorder=100, arrowstyle='fancy',
connectionstyle='Angle3',
mutation_scale=10)
ax2.add_patch(patch)
However, this does not work right out of the box currently (which
should be bug).
As a workaround, add a following line and it will work.
patch.set_annotation_clip(False)
It would be appreciated if you file a bug report for a future reference.
