Matplotlib的安裝方法請參考官方文檔:http://matplotlib.sourceforge.net/users/installing.html
為了方便大家下載,這裡提供NumPy、SciPy以及Matplotlib的下載地址:
NumPy:http://sourceforge.net/projects/numpy/files/
SciPy:http://sourceforge.net/projects/scipy/files/
Matplotlib:http://sourceforge.net/projects/matplotlib/files/matplotlib/
官方提供了Matplotlib很多示例,大家請參考:http://matplotlib.sourceforge.net/gallery.html
這裡簡單演示一個示例:
- from mpl_toolkits.mplot3d import Axes3D
- from matplotlib import cm
- from matplotlib.ticker import LinearLocator, FormatStrFormatter
- import matplotlib.pyplot as plt
- import numpy as np
- fig = plt.figure()
- ax = fig.gca(projection='3d')
- X = np.arange(-5, 5, 0.25)
- Y = np.arange(-5, 5, 0.25)
- X, Y = np.meshgrid(X, Y)
- R = np.sqrt(X**2 + Y**2)
- Z = np.sin(R)
- surf = ax.plot_surface(X, Y, Z, rstride=1, cstride=1, cmap=cm.jet,
- linewidth=0, antialiased=False)
- ax.set_zlim(-1.01, 1.01)
- ax.zaxis.set_major_locator(LinearLocator(10))
- ax.zaxis.set_major_formatter(FormatStrFormatter('%.02f'))
- fig.colorbar(surf, shrink=0.5, aspect=5)
- plt.show()
效果圖如下所示:
