Matplotlib具有相同类变量的多个动画

import matplotlib.pyplot as plt
from matplotlib.animation import FuncAnimation
import numpy as np

# 创建数据
x = np.linspace(0, 2*np.pi, 100)
y1 = np.sin(x)
y2 = np.cos(x)

# 创建画布和子图
fig, (ax1, ax2) = plt.subplots(2)

# 初始化线条对象
line1, = ax1.plot(x, y1)
line2, = ax2.plot(x, y2)

# 更新函数
def update(frame):
    # 更新数据
    line1.set_ydata(np.sin(x + frame/10))
    line2.set_ydata(np.cos(x + frame/10))
    return line1, line2

# 创建动画对象
ani1 = FuncAnimation(fig, update, frames=range(100), interval=100)
ani2 = FuncAnimation(fig, update, frames=range(100), interval=100)

# 显示动画
plt.show()
