Re: Plotting polar graph


Hi,

en = DensityPlot[Sqrt[r]*Sin[theta/2], {r, 0, 10}, {theta, -Pi, Pi},
    ColorFunction -> (ColorData["Rainbow"][#] &), PlotPoints -> 36];

Show[den /.
   GraphicsComplex[pnts_, data__] :>
    GraphicsComplex[#[[1]]*{Cos[#[[2]]], Sin[#[[2]]]} & /@ pnts, data],
   PlotRange -> All]

??

Regards
   Jens
