This time I do
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
