matplotlib三维表面图没有显示表面、matplotlib

我想作一个简单的三维表面的情节与matplotlib但情节并不在年底显现。我只能得到一个空的3D轴。 这是我做的

I am trying to make a simple 3D surface plot with matplotlib but the plot does not show at the end. I only get an empty 3D axes. Here is what I did

from mpl_toolkits.mplot3d import Axes3D

x= np.arange(1, 100, 1)

y= np.arange(1, 100, 1)

z= np.arange(1, 100, 1)

fig= figure()

ax= fig.add_subplot(111, projection ='3d')

ax.plot_surface(x, y, z, rstride= 5, cstride= 5)

show()

所以,我得到这个

So I get this

有什么建议?

推荐答案

您没有绘制表面: X 以Z 必须是二维数组。请看下面的例子: http://matplotlib.org/examples/mplot3d/surface3d_demo.html。

You are not plotting a surface: x, y and z needs to be 2D arrays. Look at this example: http://matplotlib.org/examples/mplot3d/surface3d_demo.html.
