在matplotlib中使用带有偶数个子图的sharex

Question

I have an odd number of subplots like so:

import matplotlib.pyplot as plt 

fig, axes = plt.subplots(2, 2, sharex=True)
for i, ax in enumerate(axes.flat):
    ax.plot(range(10))
fig.delaxes(axes.flat[-1])

I want them all to have the same x-axis, but easily add the x-ticks back to the plot on the right, since there is no longer a 4th plot.

It seems like there should be an easier/cleaner solution than adding each subplot manually (similar to this answer ), but I can't seem to find anything. Thanks.

Answer 1

you can use setp to make the xtick labels visible for ax[0][1] like this

import matplotlib.pyplot as plt 

fig, axes = plt.subplots(2, 2, sharex=True)
for i, ax in enumerate(axes.flat):
    ax.plot(range(10))
# for matploltib version 2.0.1
plt.setp(axes[0][1].get_xticklabels(), visible=True)
# for matplotlib version 2.1.1
axes[0][1].xaxis.set_tick_params(which='both', labelbottom=True, labeltop=False)
fig.delaxes(axes.flat[-1])
plt.show()

which will result in
