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()
