Three-Phase-Diagrams with matplotlib

Hello,

does anyone know whether it is possible to draw three-phase-diagrams with
matplotlib?

A three-phase-diagram is a triangular diagram applied in chemistry e.g. for
slags where
one has three main components of a chemical substance at the corners and
points or lines
within the triangle marking different compositions of the substances in
percent, e.g.
in metallurgy 20% Al2O3, 45% CaO and 35% SiO2.

If your percents always sum to 100, you can use a subclass of Figure I made up for soil science; pictures at

(non-soil example at end) and code at
