matplotlib share x axis but don't show x axis tick labels for both, just one


I'm using python + matplotlib and I'm having two plots share an axis. If you try to set graph1.set_xticklabels([]) while sharing an axis, it has no effect because it is shared. Is there a way to share the axis AND be able to hide the x axis of one plot?

Accepted Answer

This is a common gotcha when using shared axes.

Fortunately, there's a simple fix: use plt.setp(ax.get_xticklabels(), visible=False) to make the labels invisible on just one axis.

This is equivalent to [label.set_visible(False) for label in ax.get_xticklabels()], for whatever it's worth. setp will automatically operate on an iterable of matplotlib objects, as well as individual objects.

As an example:

import matplotlib.pyplot as plt
fig = plt.figure()
ax1 = fig.add_subplot(2,1,1)
ax1.plot(range(10), 'b-')

ax2 = fig.add_subplot(2,1,2, sharex=ax1)
ax2.plot(range(10), 'r-')

plt.setp(ax1.get_xticklabels(), visible=False)

Per a thread on matplotlib-users, you could use

import matplotlib.pyplot as plt
for ax in plt.gcf().axes:
