In Box Plots (the term first used by Tukey, 1970), ranges of values of a selected variable (or variables) are plotted separately for groups of cases defined by values of up to three categorical (grouping) variables, or as defined by Multiple Subsets categories.
In ternary plots, the triangular coordinate systems are used to plot four (or more) variables (the components X, Y, and Z, and the responses V1, V2, etc.) in two dimensions (ternary scatterplots or contours) or three dimensions (ternary surface plots).
In a categorized ternary plot, 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).

In a ternary diagram, the relative percentages of three components are plotted in an equilateral triangle, with the apexes representing 100 percent of each of the three different components.
Desert soils tend to plot in the region where a mineral cluster is intersected by a vegetation cluster.
A further refinement is to assign colors to the points in the ternary diagram, with the 100-percent mineral apex in red, the 100-percent vegetation apex in green, and the remaining 100-percent apex in blue, thereby creating a general correspondence between point colors and the general land class.

Unlike the regular scatterplot in which one variable is represented by the horizontal axis and one by the vertical axis, the multiple scatterplot consists of multiple plots and represents multiple correlations: one variable (X) is represented by the horizontal axis, and several variables (Y's) are plotted against the vertical axis.
In this type of ternary graph, the triangular coordinate systems are used to plot four (or more) variables (the components X, Y, and Z, and the responses V1, V2, etc.) in three dimensions (ternary 3D scatterplots or surface plots).

 Ternary plots
The fact that the plot of the granitic rock from the Inyos is enclosed by the Sierran field indicates that the rocks in the Inyos are part of an incomplete differentiation sequence as compared to the rocks from the Sierras.
The plots for these rocks are clustered at the extreme end of the Sierran trend which indicates that the rocks of the Alabama Hills are highly differentiated.
