Triangular Plot

Triangular Plot

Triangular plot, also known as a ternary plot, depicts the ratios of 3 variables which sums to a constant (1.0) that is positioned in an equilateral triangle. A lot of times it is used in physical sciences to show the relations between species and substances. The example above shows the data plotted in 3 bivariate cross-plots (AB, BC, AC) which translates onto the triangular diagram, where means and standard deviations are calculated.
