When you share an axis, the formatters and locators are shared as
well. I'm not sure if this is idea, but this is the way it is. If
you want to turn off the tick labels for ax2, the trick is to make
them invisible, because the tick properties are not shared. So
instead of using the NullLocator, do
for label in ax2.get_xticklabels():
label.set_visible(False)
Hope this helps,
