I am storing pickled Figures for plotting at later time but for some reason the sharedx property keeps getting lost on the 2nd (unpickled) figure. Execute the code below for a quick example. Is there a way to reset the shared x property? There is PR 1312 that talks about a potential unshare_x_axes function but there doesn't really appear to be a setting function either. This may actually be two problems though since the pickle should also maintain the sharedx property.

#!/usr/bin/env python
import cPickle as pickle
import matplotlib.pyplot as plt
import numpy as np

# Simple data to display in various forms
x = np.linspace(0, 2 * np.pi, 400)
y = np.sin(x ** 2)

f, axarr = plt.subplots(2, sharex=True)
axarr[0].plot(x, y)
axarr[0].set_title('Sharing X axis')
axarr[1].scatter(x, y)

pickle.dump(f,open('test.pickle','wb'))

new_plot = pickle.load(open('test.pickle','rb'))
new_plot.canvas.draw()

plt.show()
