Ternary diagrams are useful to visualize varying proportions of three elements. Draw them in Excel using the XLSTAT add-on statistical software.
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.
