Hi Dylan,
You're correct about the lower two triangle plots, triax.plot would handle these (although there would probably be a bit of hacking about to get the two plots in the right place). I don't understand the upper rhombus. As a third triangle plot I can get it, but the bottom half seems to be either redundant or nonsensical (you can't have negative proportions of components). If I have some time, I'll look up "piper plot" and try to work out what it all means.
