  • $\begingroup$ What is the definition for function f[x, y, 1 - y] you have plotted? $\endgroup$ Commented Jan 3, 2014 at 17:54
  • $\begingroup$ Ugh, it took me forever to find the transform, +1. $\endgroup$ Commented Jan 3, 2014 at 18:09
  • $\begingroup$ Is the range you've used for f correct for a ternary plot? I thought the sum of the arguments needs to be <= 1. $\endgroup$ Commented Jan 3, 2014 at 18:19
