动画的制作是基于matplotlib的animation，对于一条线的绘制，网上的教程很多，这里不介绍，主要介绍一下一图多线的情况。
```python # 导入相关库 import seaborn as sns import matplotlib.pyplot as plt import matplotlib.animation as animation
# 生成数据 x1 = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] y1 = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] x2 = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] y2 = [0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 0.10]
# 简单设置一下绘图基本参数 sns.set_style('darkgrid')
# 绘图 fig, ax = plt.subplots() ax.set_title('draw lines') ax.set_xlabel('x') ax.set_ylabel('y') ln1, =ax.plot([], [], 'r-o', animated=False) ln2, =ax.plot([], [], 'r-o', animated=False) ax.legend(['y1, y2'], loc='upper left')
def update(frame): x_1 = x1[0:frame] y_1 = x1[0:frame] x_2 = x1[0:frame] y_2 = x1[0:frame] ln1.set_data(x_1, y_1) ln2.set_data(x_2, y_2) return ln1, ln2,
ani = animation.FuncAnimation(fig, update, frames=len(x1)+1, interval=300, blit=True)
plt.show() ```
绘制的图像如下：
