3D Ternary Plots - 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 using a first, second, full cubic or special cubic polynomial fit (see 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.
