在python中如何使用相同的轴在同一图形上绘制多个信号？

import matplotlib.pyplot as plt
import numpy as np

# 生成示例数据
x = np.linspace(0, 10, 100)
y1 = np.sin(x)
y2 = np.cos(x)
y3 = np.tan(x)

# 创建图形和轴对象
fig, ax = plt.subplots()

# 绘制信号
ax.plot(x, y1, label='Signal 1')
ax.plot(x, y2, label='Signal 2')
ax.plot(x, y3, label='Signal 3')

# 添加图例
ax.legend()

# 设置标题和轴标签
ax.set_title('Multiple Signals')
ax.set_xlabel('X-axis')
ax.set_ylabel('Y-axis')

# 显示图形
plt.show()
