Probing a plot based on colormap information
20 views (last 30 days)
How can I probe a plot with colormap data?
As you see, in this case, it only shows the xyz coordinates which is not really useful. I want to be able to see the colormap value (between 0 and 1).
Any ideas? I am using the trisurf function.

Try function datatip & dataTipTextRow if your MATLAB version is after 2019b.
[x,y] = meshgrid(1:15,1:15);
z = peaks(15);
T = delaunay(x,y);
s = trisurf(T,x,y,z);
dt = datatip(s);
s.DataTipTemplate.DataTipRows(end+1) = dataTipTextRow('Colormap Value',T,'%.1f');

I don't think you would be able to see the values like that. But you can see what value it has using:
F = scatteredInterpolant(x,y,z,c) ;
ci = F(xi,yi,zi) ; % where xi, yi, zi is the picked point
