Two programs:
I've just started using Jamie Connolly's Perplex program available at:
http://www.perplex.ethz.ch/12/16/2002
Its not too hard to figure out with the available literature.
It compute ternary plots that are viewable in Adobe illustrator
Also, ternplot available on Daniel Marshall's webpage:
http://www.sfu.ca/~marshall/ternplot.htm
is a good microsoft excel spreadsheet.
Cheers,
Toti..
