使用Matplotlib绘制动画股票的价格

import matplotlib.pyplot as plt
import matplotlib.animation as animation
import pandas as pd

# 假设有一个包含股票价格的DataFrame数据
df = pd.DataFrame({'Date': ['2022-01-01', '2022-01-02', '2022-01-03'],
                   'Price': [100, 120, 90]})

def animate(i):
    # 清空当前图形
    plt.clf()
    
    # 绘制股票价格走势图
    plt.plot(df['Date'][:i+1], df['Price'][:i+1])
    
    # 设置图表标题和坐标轴标签
    plt.title('Stock Price Animation')
    plt.xlabel('Date')
    plt.ylabel('Price')
    
    # 设置图表范围
    plt.xlim(df['Date'][0], df['Date'][len(df)-1])
    plt.ylim(min(df['Price']), max(df['Price']))

ani = animation.FuncAnimation(plt.gcf(), animate, frames=len(df), interval=1000)

plt.show()
