This time I do :slight_smile:

The axis doesn't share everything -- it shares a locator and the view
limits. When you do ylim([]) you are telling the y tick locator to
use no ticks, and this is shared. There is a workaround -- no
terribly elegant but servicable, and one I use all the time.

Suppose ax1 and ax2 share the xaxis and you only want tick labels on

ax1 = fig.add_subplot(211)
ax2 = fig.add_subplot(212, sharex=ax1)

for label in ax1.get_xticklabels():

The key idea is that the actual ticks are not shared (they can't be
because their y locations are different). But their x locations are
shared (which is why ax1.set_xlim([]) doesn't do what you want. But
you can set the visibility property to make them invisible, which

Should be a recipe in the cookbook, enterprising mailing list readers.
