Diagramas ternarios

This visualization method 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 allows only the second approach.
