如何使用Matplotlib绘制带时间戳的动态数据

import matplotlib.pyplot as plt
import matplotlib.animation as animation
from datetime import datetime

fig, ax = plt.subplots()

data = []
timestamps = []

def update_data():
    # 获取当前时间戳
    timestamp = datetime.now().strftime('%H:%M:%S')
    # 生成随机数据（示例）
    value = random.randint(0, 100)
    # 添加数据和时间戳到列表中
    data.append(value)
    timestamps.append(timestamp)

def update_chart(frame):
    # 清空图表
    ax.clear()
    # 绘制数据
    ax.plot(timestamps, data)
    # 设置x轴标签为时间戳
    ax.set_xlabel('Timestamp')
    # 设置y轴标签
    ax.set_ylabel('Value')
    # 设置标题
    ax.set_title('Dynamic Data with Timestamp')

ani = animation.FuncAnimation(fig, update_chart, frames=range(10), interval=1000)

plt.show()
