为pandas数据结构绘制线性图

import matplotlib.pyplot as plt

import numpy as np

import pandas as pd

data = {'series1':[1,3,4,3,5],

            'series2':[2,4,5,2,4],

            'series3':[3,2,3,1,3]}

df = pd.DataFrame(data)

x =  np.arange(5)

plt.axis([o,5,o,7])

plt.plot(x,df)

plt.legend(data,loc=2)

plt.show()
