如何在使用matplotlib直方图时旋转轴标签？

import matplotlib.pyplot as plt

data = [1, 2, 3, 4, 5]
plt.hist(data)

ax = plt.gca()

x_tick_labels = ax.get_xticklabels()

ax.set_xticklabels(x_tick_labels, rotation=45)

import matplotlib.pyplot as plt

data = [1, 2, 3, 4, 5]
plt.hist(data)

ax = plt.gca()
x_tick_labels = ax.get_xticklabels()
ax.set_xticklabels(x_tick_labels, rotation=45)

plt.show()
