3D Ternary Plots - Deviation

This type of ternary graph allows you to examine the relations between four or more dimensions (X, Y, Z, and V1, V2, etc.) as "deviations" from a specified base-level of the V-axis where three of those dimensions (X, Y, and Z) represent components of a mixture (i.e., the relations between them is constrained such that the values of the three variables add up to the same constant for each case).
