In this type of ternary graph, you can examine the relations between four or more dimensions (X, Y, Z, and V1, V2, etc.) as a 3D trace plot categorized by 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).
