Surface Plots: Visualize Trending Performance

Surface Plots display trending performance among three numeric variables. They are used to identify trends, and outliers within numeric surfaces. The Surface is made up of a series of points, where each point has an:

• X Position
• Y Position
• Color (which represents the Z Axis)

Allows for comparisons between subsets of data 

The Surface Plot can support data sets where the X and Y positions can both be regular and irregular in their distribution. Additionally, the color scale can be continuous, or stepped to show a surface gradient. Surface plots are useful for visualizing matrices that are too large to display in numerical form and for graphing functions of two variables.
