python绘制已知点的坐标的直线实例

如下所示：

import matplotlib.pyplot as plt
import numpy as np


     
x = [11422,11360,11312,11274,11233,11196,11160,11129,11098,11038,
   10984,10944,10903,10863,10828,10789,10752,10715,10675,10639,
   10654,10619,10587,10550,10510,10466,10425,10389,10350,10311,
   10272,10237,10196,10161]
   
y = [123,120,115,110,105,100,95,90,85,80,
  75,70,65,60,55,50,45,40,35,30,
  25,20,15,10,5,0,-5,-10,-15,-20,
  -25,-30,-35,-39.6]
plt.plot(x, y, 'r-o')
# plt.plot(x, y)
plt.show()
