win7,python3.7下调试画图，没有什么问题

import math

(相关资料图)

from pylab import plot,show

x=[1,2,3]

y=[2,4,6]

plot(x,y,marker='o')

show()

import math

from pylab import plot,show

nc2000=[31.3,37.3,47.2,51.0,63.5,71.3,72.3,72.7,66.0,57.0,45.3,31.1]

nc2006=[40.9,35.7,43.1,55.7,63.1,71.0,77.9,75.8,66.6,56.2,51.9,43.6]

nc2012=[37.3,40.9,50.9,54.8,65.1,71.0,78.8,76.7,68.8,58.0,43.9,41.5]

month=range(1,13)

plot(month,nc2000,month,nc2006,month,nc2012)

show()

画图的时候x,y的维数必需一致。（标红的句子书本上是range(1,12)报错）

之后函数作图基本上可以自定义一个

def draw(x,y):
