'''
======================
3D surface (color map)
======================
Demonstrates plotting a 3D surface colored with the coolwarm color map.
The surface is made opaque by using antialiased=False.
Also demonstrates using the LinearLocator and custom formatting for the
z axis tick labels.

某种程度上,可以在打印之前运行此代码片段:
当前发现了一个打开的问题here。
这是自matplot版本2.2.2Whats new | github以来的正式版本
因此,要绘制透视正交图,您必须添加
proj_type = 'ortho'
,然后您应该具有类似的内容:示例图片
