Plotting and analyzing data trends in ternary diagrams made easy

Ternary plots are used in many fields of science to characterize a system based on three components. Triangular plotting is thus useful to a broad audience in the Earth sciences and beyond. Unfortunately it is typically the most expensive commercial software packages that offer the option to plot data in ternary diagrams. However, they lack features that are paramount to the geosciences, such as the ability to plot data directly into a standardized diagram and the possibility to analyze temporal and stratigraphic trends within this diagram.
