How to plot data points above and below the surface in a ternary plot in 3D?

Hello, I have a question. Is there a way to plot, in addition to the surface, some data points in 3 D and not in 2D in a ternary plot? And also to plot them in different colors according if they are below or above the surface ? I successed to plot the surface:
ternsurf(XA,XB,XC,f3);ternlabel('Trifluoperazine', 'Gemcitabine', 'Paclitaxel');
c = colorbar();
but I cannot plot data points in 3 D, the data points were plotted on the base of the ternary plot in 2 D with the command below (figure attached):
ternplot(XA, XB, XC,'marker', 'd','markerfacecolor','yellow','markersize',5); ternlabel('Trifluoperazine', 'Gemcitabine', 'Paclitaxel');
And I would like them in 3D, so I tried the commands below, but it does not work. Do you have an idea ?
%%%%%%%%%points above the surface %%%%%%%%%%
%%%%%%%%%points below the surface %%%%%%%%%%
ternplot(Xabove, Yabove, Zabove, 'd','red'); ternlabel('TFP', 'GEM', 'PTX');
ternplot(Xbelow, Ybelow, Zbelow, 'd','green'); ternlabel('TFP', 'GEM', 'PTX');

'ternplot' is ternary version of 'plot' command. You can plot 3d points using 'plot3' after creating the ternary axis with a 'ternsurf' command as follows: ternsurf(XA, XB, XC, f3); [x, y] = terncoords(XA, XB, XC); hold on; plot3(x, y, f3); hold off;
