在Paul的幫助下,我已經爲我的應用修改了mplot3d example code。代碼如下:用於matplotlib的色標plot_surface命令
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import numpy as np
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
u = np.linspace(0, 2 * np.pi, 100)
v = np.linspace(0, np.pi, 100)
x = 10 * np.outer(np.cos(u), np.sin(v))
y = 10 * np.outer(np.sin(u), np.sin(v))
z = 10 * np.outer(np.ones(np.size(u)), np.cos(v))
z1 = z * np.cos(0.5*x)
N = z1/z1.max() # normalize 0..1
surf = ax.plot_surface(x, y, z, rstride=1, cstride=1, facecolors=cm.jet(N), linewidth=0, antialiased=False, shade=False)
fig.colorbar(surf, shrink=0.5, aspect=5)
plt.show()
代碼的偉大工程,以繪製表面。但是,當我嘗試將彩條添加到上述情節,我得到以下錯誤:
Traceback (most recent call last):
File "<ipython console>", line 1, in <module>
File "C:\Python26\lib\site-packages\spyderlib\widgets\externalshell\startup.py", line 122, in runfile

我會如此感激,如果有人能指導我這個問題。

你更容易找到誰知道一個matplotlib郵件列表上的這些具體細節。 –
