Does anyone know of Mac software that facilitates
plotting in triangular coordinates?

Thanks,

Igor comes with a Macro package that can plot ternary diagrams: i.e.,
a plot of x+y+z=c on an equilateral triangle.  It works superbly for
us.  It is intuitive if you are accustomed to engineering plotting
packages such as Tellagraf, but otherwise be prepared to read the
manual before putting it in the back of the drawer.  Igor still
has the best quality output of all the packages we have
(Kaleidograph, DeltaGraph, Trapeze, Cricket (ugh) Graph), but the
notation does take getting used to.
