I am seeing this same error when generating multiple ternary plots that have a categorical term in the prediction formula. Can someone please help to resolve?

How are you trying to make the ternary plot? You may not add non-numeric (i.e., Categorical Factors) when selecting Graph > Ternary Plot.

Use the built-in Mixture Profiler in Fit Least Squares or on its own through Graph > Mixture Profiler should accommodate the categorical factor:

I tried to make the ternary plot with an expression that had categorical data in the prediction formula and use the group by in the ternary plot window with that categorical factor.

Can you fill in above or below on a mixture profiler contour for aesthetic purposes?
