Hi there, I'm trying to reproduce this very cool figure: http://en.wikipedia.org/wiki/File:NaturalLogarithmRe.png Problem: I can't get the contour lines color-matched to the 3D surface, which is colored according to it's height. My code is below, can anyone help? Module[{f}, f[x_, y_] := Log[x + I y]; logre = Show[Plot3D[Re[f[x, y]], {x, -2.4, 2.4}, {y, -2, 2}, PlotStyle -> Opacity[0.7], Axes -> True, Boxed -> True, PlotRange -> {Automatic, Automatic, {-3, 4}}, ColorFunction -> (Blend[{Yellow, Purple}, #3] &)], Graphics3D[ ContourPlot[Re[f[x, y]], {x, -2.4, 2.4}, {y, -2, 2}, Axes -> False, ContourShading -> None, ContourStyle -> Purple][[ 1]] /. {x : _Real, y : _Real} -> {x, y, -3}], ViewPoint -> {2.2, -4, 1.3}, ImageSize -> 300 ] ]
