Python基於matplotlib實現繪製三維圖形功能樣本，pythonmatplotlib

本文執行個體講述了Python基於matplotlib實現繪製三維圖形功能。分享給大家供大家參考，具體如下：

代碼一：

# coding=utf-8import numpy as npimport matplotlib.pyplot as pltimport mpl_toolkits.mplot3dx,y = np.mgrid[-2:2:20j,-2:2:20j]#測試資料z=x*np.exp(-x**2-y**2)#三維圖形ax = plt.subplot(111, projection='3d')ax.set_title('www.jb51.net - matplotlib Demo');ax.plot_surface(x,y,z,rstride=2, cstride=1, cmap=plt.cm.Blues_r)#設定座標軸標籤ax.set_xlabel('X')ax.set_ylabel('Y')ax.set_zlabel('Z')plt.show()

運行結果：

 

代碼二：

# coding=utf-8import pylab as plimport numpy as npimport mpl_toolkits.mplot3drho, theta = np.mgrid[0:1:40j,0:2*np.pi:40j]z = rho**2x = rho*np.cos(theta)y = rho*np.sin(theta)ax = pl.subplot(111, projection='3d')ax.set_title('www.jb51.net - matplotlib Demo');#ax.plot_surface(x,y,z)ax.plot_surface(x,y,z,rstride=2, cstride=1)#設定座標軸標籤ax.set_xlabel('X')ax.set_ylabel('Y')ax.set_zlabel('Z')pl.show()

運行結果：
