how to plot 3d ternary plot for three mixtures

问题

I have tried with your terndemo but I'm unable get a graphical data like you sir. My aim is to present that how, each formulation is responsible for different zetasizes in 3d ternary plot. I tried like editing the file of yours but the result is different.

ternsurf(A, B, data);

I've updated this to match your data. Note that the last row of your coordinates doesn't add to 100. I've divided it by 100 and plotted a pcolor plot rather than a 3D surface since I think it's clearer with your data. If you want a 3d surface, you just need to divide the data column by around 1000 to get the correct scale and use ternsurf.

A = experimental(:, 1)';
B = experimental(:, 2)';
C = 1 - (A + B);

ternpcolor(A, B, data);
shading interp
ternlabel('oil', 'surf', 'cosurf');
colorbar

This results in the following plot:
