Ternary diagrams

When to use Ternary Diagrams?

Ternary Diagrams are a visualization method that is particularly useful in domains where one works with three elements with varying proportions, for example in chemistry or petrology.

This tool lets you quickly create a ternary diagram representing points and the projection lines connecting each point to each axis.

There are two approaches for ternary graphs:

• Either segments corresponding to the orthogonal projection of the points on the axes give the information on the relative proportions of the three elements. 
• Or the projection parallel to the axis A onto the axis B corresponds to the coordinate of the point along the axis B, where B is after A when turning counterclockwise. 

XLSTAT currently only allows the second approach.
