Matplotlib:如何对大数据集的pcolormesh网格进行动画处理

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

# 生成示例数据
x = np.linspace(0, 10, 100)
y = np.linspace(0, 10, 100)
X, Y = np.meshgrid(x, y)
Z = np.sin(X) + np.cos(Y)

# 创建图表对象
fig = plt.figure()
# 创建网格绘图对象
grid = plt.pcolormesh(X, Y, Z)

def update(frame):
    # 更新网格数据集
    Z_new = np.sin(X + frame/10) + np.cos(Y + frame/10)
    grid.set_array(Z_new.ravel())
    return grid,

# 创建动画对象
ani = animation.FuncAnimation(fig, update, frames=100, interval=100)

# 显示动画
plt.show()
