Daniel,
I found that I came across this often, so I created three functions (one for
sharing x, one for y, and one for both). In looking over them right now, there
may be some inconsistencies between their style, but the idea is there. I am
pasting them below in case they are useful to someone else. The original ideas
came from figure.autofmt_xdate.

def autofmt_sharexy(fig=None):
if fig==None:
fig = gcf()
for a in fig.axes:
if a.is_first_col():
if not a.is_first_row():
a.get_yticklabels()[-1].set_visible(False)
else:
for yl in a.get_yticklabels():
yl.set_visible(False)
a.set_ylabel('')
if not a.is_last_row():
for xl in a.get_xticklabels():
xl.set_visible(False)
a.set_xlabel('')
else:
if not a.is_last_col():
a.get_xticklabels()[-1].set_visible(False)
subplots_adjust(hspace=0,wspace=0)

fig = gcf()

a.set_ylabel('')

a.get_xticklabels()[0].set_visible(False)
if not trim_xlabel:
a.xaxis.set_major_locator(MaxNLocator(6))
xtl = a.get_xticklabels()
setp(xtl[0::2],visible=False)

for i,ax in enumerate(fig.axes):
