Ternary Plots in MATLAB^®

How to make Ternary Plots in MATLAB^® with Plotly.

To make this plot, you'll need the the Ternplot package
from the MATLAB^® File exchange

Ternary Contour Plot

A = [0 .2 .2 .2 0 .6 .75 .9 0 1 .8 .3];
B = [1 .2 .4 .1 0 .4 .05 0 .8 0 .05 .3];
C = [0 .6 .4 .7 1 0 .2 .1 .2 0 .15 .4];
Z = [.1 .5 .1 .2 1 .8 .4 0 .1 .6 1 .7];

fig = figure;
terncontour(A, B, C, Z)
ternlabel('A', 'B', 'C')

fig2plotly(fig, 'strip', false);
