Surface Chart

Surface Chart (3D Surface Plot) displays a set of three-dimensional data as a mesh surface. It is useful when you need to find the optimum combinations between two sets of data.

The colors and patterns in Surface Charts indicate the areas that are in the same range of values by analogy with a topographic map.

A typical 3D Surface Plot is constructed from three variables: X, Y, and Z. Two of them are independent, located on the horizontal axes. The other is dependent, shown along the vertical axis. Hence, Surface Charts represent a functional relationship between a designated dependent variable and two independent ones.
