Increasing level of contours on ternary plot

tntjennings — Wed, 15 Nov 2023 20:26:30 GMT

Hi all,

I need to use a ternary plot since I've run a mixture DOE with 3 variables, I can use my prediction formula to show on my ternary plot but it looks like its locked at 5 levels. I'd really like to have 6 or 7 levels. I don't see the options typical in graph builder or when doing a contour plot. Anyway do increase levels on a ternary plot? Thanks in advance!

I'm using JMP 17.0.0

You are correct, The Ternary Plot provides only five levels for contours. The Mixture Profile provides a variable number of contour lines. Click the red triangle and select Countour Grid. You then specify the minimum, maximum, and increment for the lines.

Hi Mark,

Thank you for the response. Is there anyway to color in the mixture plot for different contours like in the ternary plot? I'd like to use these for a poster with the goal that someone not familiar with JMP could understand. The contours on the ternary plot essentially make a heat map that is easy for anyone to quickly understand, the mixture contours just as line, not so much. A couple of my steps really need that 6/7 levels of color to showcase what we're trying to do. Also open to others way to show the results from a mixture DOE in an easy to understand way. Thanks again for the help!

One option with the mixture profiler would be to generate several identical prediction formula columns (equal to however many levels you want to show in the ternary plot) and then add different high or low level limits as shown below.

Unfortunately the colors become a bit muted due to the overlay of the different colors, but perhaps someone can identify a way of avoiding this.
