Plotting the function on a Sphere?

Let me explain, what I'm actually solving.

I'm solving Diffusion-Reaction equation(3D) in spherical coordinates.

I'm solving this equation numerically. So at the end I'm getting , r, θ, ϕ.

So I want to plot this function on a sphere( - plane) instead of palne

Can anyone help in this regard?

Thanks in advance.

[KSSV]

r = 1 ;
th = linspace(0,2*pi) ;
phi = linspace(0,pi) ;
[T,P] = meshgrid(th,phi) ;
X = r*cos(T).*sin(P) ;
Y = r*sin(T).*sin(P) ;
Z = r*cos(P) ;
surf(X,Y,Z)
axis equal

But where we plot C?

What do you think: why does the surface of the sphere have different colors ?
