直接在命令行下输入命令就可以完成安装

运行demo.py 查看效果

from mpl_toolkits.mplot3d import Axes3D

from matplotlib import cm

from matplotlib.ticker import LinearLocator

import matplotlib.pyplot as plt

import numpy as np

fig = plt.figure()

ax = fig.gca(projection='3d')

[x, t] = np.meshgrid(np.array(range(25))/24.0, np.arange(0, 575.5, 0.5)/575*17*np.pi-2*np.pi)

p = (np.pi/2)*np.exp(-t/(8*np.pi))

u = 1-(1-np.mod(3.6*t, 2*np.pi)/np.pi)**4/2

y = 2*(x**2-x)**2*np.sin(p)

r = u*(x*np.sin(p)+y*np.cos(p))

surf = ax.plot_surface(r*np.cos(t), r*np.sin(t), u*(x*np.cos(p)-y*np.sin(p)), rstride=1, cstride=1, cmap=cm.gist_rainbow_r,linewidth=0, antialiased=True)

plt.show()
