多行python动画

我试图显示一个Python2.7MatPlotLib图形，动画显示2行，循环遍历11个文件，每个文件包含不同的月份数据

线路数据保存在称为CoinMarketData[i]的数据帧中，用于帧1到11，在“Log MC”和“Log EMC”列中

到目前为止，我掌握的代码是：

fig = plt.figure()
ax = plt.axes(xlim=(0,100), ylim=(0,30))
N=11
lines = [plt.plot([], [])[0] for _ in range(N)]

def init():
    for line in lines:
        line.set_data([],[])
    return lines

def animate(i):
    for j,line in enumerate(lines):
        # I think i need to put lists of the X and Y data in here
        lines.set_data(x, y) # set_data only takes 2 arguements...how do i set both y and y2 to the lines?
    return lines

anim = animation.FuncAnimation(fig, animate, init_func=init,
           frames=100, interval=20, blit=True)

plt.show()

如果想要有两行，不要创建其中的11行。由于每行属于一列，因此可以单独设置数据

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

N=11

dataframes = [pd.DataFrame({"x":np.sort(np.random.rand(10)*100),
                            "y1":np.random.rand(10)*30,
                            "y2":np.random.rand(10)*30}) for _ in range(N)]

fig = plt.figure()
ax = plt.axes(xlim=(0,100), ylim=(0,30))

lines = [plt.plot([], [])[0] for _ in range(2)]

def animate(i):
    lines[0].set_data(dataframes[i]["x"], dataframes[i]["y1"])
    lines[1].set_data(dataframes[i]["x"], dataframes[i]["y2"])
    return lines

anim = animation.FuncAnimation(fig, animate, 
           frames=N, interval=20, blit=True)

plt.show()
