用python画图很多是根据z=f(x,y)来画图的,本博文将三个对应的坐标点输入画图:
散点图:
1
2
3
4
5
6

import matplotlib.pyplot as plt from mpl_toolkits.mplot3d import Axes3D fig = plt.figure() ax = fig.add_subplot( 111 , projection = '3d' ) X = [ 1 , 1 , 2 , 2 ] Y = [ 3 , 4 , 4 , 3 ] Z = [ 1 , 2 , 1 , 1 ] ax.scatter(X, Y, Z) plt.show() |
曲面图:
