Python Matplotlib 双轴移动，多图布局

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(- np.pi, np.pi, 50)
plt.rcParams['axes.unicode_minus'] = False
plt.figure(figsize=(9, 6))
# 绘制了2个图形，成对出现 plt.s
plt.plot(x, np.sin(x), x, np.cos(x))

ax = plt.gca()

ax.spines['right'].set_color('white')
ax.spines['top'].set_color('#FFFFFF') # rgb 白色 🤍

ax.spines['bottom'].set_position(('data',0))
ax.spines['left'].set_position(('data',0))

plt.yticks([-1, 0, 1],labels=['-1','0','1'],fontsize=15)

_ = plt.xticks([-np.pi, -np.pi/2, np.pi/2, np.pi],labels=['-π','-π/2','π/2','π'],fontsize=15)
