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

조회 수: 5 (최근 30일)
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 %%%%%%%%%%
above=datacombinationall(C>Cf3,:)
Xabove=((above(:,1))./IC50A)./TT;
Yabove=((above(:,2))./IC50B)./TT;
Zabove=((above(:,3))./IC50C)./TT;
%%%%%%%%%points below the surface %%%%%%%%%%
below=datacombinationall(C<Cf3,:)
Xbelow=((below(:,1))./IC50A)./TT;
Ybelow=((below(:,2))./IC50B)./TT;
Zbelow=((below(:,3))./IC50C)./TT;
% %
ternplot(Xabove, Yabove, Zabove, 'd','red'); ternlabel('TFP', 'GEM', 'PTX');
hold on
ternplot(Xbelow, Ybelow, Zbelow, 'd','green'); ternlabel('TFP', 'GEM', 'PTX');
Yours sincerely,

'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;

Hello, I have another question because it seems that the caculation of the surface is wrong with the ter n surf. I try with tersurf. Is it possible to plot some data points in 3D also with ternaryc function ?
My surface is defined :
[hg,htick,hcb]=tersurf(XA,XB,XC,f3);
and then I plot the points:
hold on
[h,hg,htick]=terplot;
colormap(jet)
hter=ternaryc(XA,XB,XC);
set(hter,'marker','o','markerfacecolor','yellow','markersize',4)
Yours sincerely,
