level is a (120,4) matrix. The columns correspond from 1 to 4 to X coordinate, Y coordinate, Z coordinate and a C scalar value.
When I use this code:
x = level(:,1);
y = level(:,2);
z = level(:,3);
xv = linspace(min(level(:,1)), max(level(:,1)), 20);
yv = linspace(min(level(:,2)), max(level(:,2)), 20);
[X,Y] = meshgrid(xv, yv);
Z = griddata(x,y,z,X,Y);
hold on
surf(X, Y, Z);
grid on
shading interp
axis equal
colorbar
I obtain this plot:

I would like to obtain a surface which is located exactly as I located this one, following the Z values of hight, but that the colors represent C values and not Z.
The colors of the surf plot should be folliwng this:

Any ideas about how to do it?

Use cdata property
[x,y,z] = peaks(20);
c = sphere(19);
surf(x,y,z,'cdata',c)
