Did you create an interpolation function from your data? data = Flatten[Table[{t, p, Sqrt[p^2 + t^2]}, {t, 0, 2 Pi, Pi/16}, {p, 0, Pi, Pi/32}], 1]; f = Interpolation[data]; SphericalPlot3D[1, {t, 0, 2 Pi}, {p, 0, Pi}, ColorFunction -> Function[{x, y, z, t, p, r}, Hue[f[t, p]]], Mesh -> 10, MeshFunctions -> {Function[{x, y, z, t, p, r}, f[t, p]]}] Comparing with the original function SphericalPlot3D[1, {t, 0, 2 Pi}, {p, 0, Pi}, ColorFunction -> Function[{x, y, z, t, p, r}, Hue[Sqrt[p^2 + t^2]]], Mesh -> 10, MeshFunctions -> {Function[{x, y, z, t, p, r}, Sqrt[p^2 + t^2]]}] Bob Hanlon On Mon, Nov 11, 2013 at 12:05 AM, Danny Barker <danny.barkan at gmail.com>wrote: > Dear all > > I have a data set in the form of a list: { > {Theta1,Phi1,f1},{Theta2,Phi2,f2}, ... } which i would like to present as a > density/Contour plot on the surface of a sphere > > i read past posts and tried using > > SphericalPlot3D[1, {t, 0, 2 Pi}, {p, 0, Pi}, > ColorFunction -> Function[{x, y, z, t, p, r}, Hue[f[t, p]]], > Mesh -> 10, MeshFunctions -> {Function[{x, y, z, t, p, r}, f[t, p]]}] > > but can't seem to get it right... > > thanks in advance for your help > >
