Let's say, I have many spheres drawn with surf/mesh.

I want to display customize data values rather than x,y,z. All values will be different for different spheres and clicking on any point on a particular sphere should display the same data. Refer figure. How do I achieve it?

So far, I'm thinking of using Surface property 'tag' to assign unique string to each sphere. Is there any better way to do it?

    [x,y,z] = sphere;
    a=[3 1 3 1];
    s1=surf(x*a(1,4)+a(1,1),y*a(1,4)+a(1,2),z*a(1,4)+a(1,3),...
            'FaceColor', [1 0 0],'FaceLighting','flat','EdgeColor','none');
    s1.Tag = '1';
