matplotlib共用x轴标签旋转问题

Question

目标是把这个图的x轴标签数字全部旋转90度。

 import numpy as np
import matplotlib.pyplot as plt

t = np.arange(0.01, 10.0, 0.01)
data1 = np.exp(t)
data2 = np.sin(2 * np.pi * t)

fig, ax1 = plt.subplots()

color = 'tab:red'
ax1.set_xlabel('time (s)')
ax1.set_ylabel('exp', color=color)
ax1.plot(t, data1, color=color)
ax1.tick_params(axis='y', labelcolor=color)

ax2 = ax1.twinx()  

color = 'tab:blue'
ax2.set_ylabel('sin', color=color)  
ax2.plot(t, data2, color=color)
ax2.tick_params(axis='y', labelcolor=color)
plt.xticks(rotation=50) #如果不是共用轴，就可以设置。现在共用X轴就无法使用xticks的rotation来对x周标签旋转
fig.tight_layout()  
plt.show()

Answer 1

把代码中这句plt.xticks(rotation=50)改成下面，

 for xtick in ax1.get_xticklabels():
    xtick.set_rotation(50)

x轴的坐标就rotate了
