同一图表上的多个绘图- Matplotlib

import matplotlib.pyplot as plt
import numpy as np

# 创建数据
x = np.linspace(0, 10, 100)
y1 = np.sin(x)
y2 = np.cos(x)

# 创建 Figure 和子图
fig, axs = plt.subplots(2, 1, figsize=(8, 6))

# 在第一个子图上绘制正弦曲线
axs[0].plot(x, y1, label='Sine')
axs[0].set_title('Sine Wave')
axs[0].legend()

# 在第二个子图上绘制余弦曲线
axs[1].plot(x, y2, label='Cosine', color='red')
axs[1].set_title('Cosine Wave')
axs[1].legend()

plt.tight_layout()
plt.show()
