matplotlib - 子图隐藏 xlabel

Question

当我在 IPython 中运行它时：

r = (100, 300)
b = 100
plt.figure(figsize=(8, 6))
plt.subplot(3,1,1)
plt.xlabel('Picker time (ms)')
plt.hist(sequential['X0'], range=r, bins=b, color='blue')
plt.subplot(3,1,2)
plt.hist(stateful['X0'], range=r, bins=b, color='green')
plt.subplot(3,1,3)
plt.hist(standard['X0'], range=r, bins=b, color='red')

第一个情节的xlabel文本在第二个情节下丢失了。这是情节：

你可以看到“P”的顶部伸出来。如何在xlabel不发生这种情况的情况下为子图提供 s？

Answer 1

您可以使用plt.tight_layout()调整子图，使 x-label 可见。

Answer 2

As an alternative to @Molly's excellent suggestion a more manual approach is to use

plt.subplots_adjust(hspace=0.1)

Since your x axes are all the same, I would suggest setting hspace=0.0 and removing the x axis labels (use plt.set_xticklabels([])). This saves space and reduces the amount of repeated information.
