Python 入门练习--Axes3D 画3D图 

 1 import numpy as np
 2 import matplotlib.pyplot as plt
 3 from mpl_toolkits.mplot3d import Axes3D # used for 3d plot
 4 
 5 x = np.linspace(0,100,50)
 6 y = np.linspace(0,100,50)
 7 x,y = np.meshgrid(x,y)
 8 z = x**2 + y**2
 9 
10 figure1 = plt.figure() # create a figure
11 ax = figure1.gca(projection='3d')   # define figure as 3d
12 ax.scatter(x,y,z) # define the three axes
13 ax.set_xlabel('X index')
14 ax.set_ylabel('Y index')
15 ax.set_zlabel('Z index')
16 
17 plt.savefig('fig1.png',format='png',dpi=100)
