3D Ternary Plots - Categorized Contour/Lines

In this type of ternary graph, the three-dimensional surface (fitted to a four-coordinate data set) is projected onto a two-dimensional plane as a line contour for each level of the grouping variable (or user-defined subset of data). One component graph is produced for each level of the grouping variable (or user-defined subset of data) and all the component graphs are arranged in one display to allow for comparisons between the subsets of data (categories).

For more information about ternary representation of data, see Ternary Plots and Fitting Options for Ternary Plots.

In order to change the range of values and number of levels used to define the contour or surface, see Surface Specifications.
