What is a 3D surface chart?

 

3-D Surface chart shows a 3-D view of the data, which can be imagined as a rubber sheet stretched over a 3-D Column chart. It is typically used to show relationship between large amount of data that may otherwise be difficult to see. Color bands in a surface chart indicate the difference between values.
