使用Matplotlib查询制作直方图动画

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

data = np.random.randn(1000)  # 生成1000个服从正态分布的随机数

fig, ax = plt.subplots()
hist, bins, _ = ax.hist(data, bins=30)  # 绘制直方图

def update(frame):
    ax.cla()  # 清除当前轴
    ax.hist(data[:frame], bins=bins)  # 绘制截止到当前帧的直方图
    ax.set_title('Histogram Animation')  # 设置标题
    ax.set_xlabel('Value')  # 设置x轴标签
    ax.set_ylabel('Frequency')  # 设置y轴标签

ani = animation.FuncAnimation(fig, update, frames=range(1, len(data)+1), interval=100, repeat=False)

plt.show()
