I've realized that using the ParasiteAxes from the mpl_toolkits should do
exactly what I'm asking. However, I am having a problem with callbacks when
the x and y limits change (try resizing the window). The following script
shows that the callback for the second set of axes is not carried out. Is
this a bug, or a limitation? Or something I'm doing wrong?
Thanks!

import matplotlib.pyplot as mpl
import numpy as np
import mpl_toolkits.axes_grid.parasite_axes as mpl_toolkit
def check_callback(ax):
print "callback for ",ax.name
array = np.random.random((100,100))
fig = mpl.figure()
ax = mpl_toolkit.SubplotHost(fig,1,1,1,adjustable='datalim')
ax.name = "first axis"
ax.callbacks.connect('xlim_changed',check_callback)
ax.callbacks.connect('xlim_changed',check_callback)
ax2 = ax.twin()
ax2.name = "second axis"
ax2.callbacks.connect('ylim_changed',check_callback)
ax2.callbacks.connect('ylim_changed',check_callback)
fig.add_axes(ax)
ax.imshow(array,interpolation='nearest')
fig.canvas.draw()
