Here's one way, albeit using the PolarDraw function from David Park's "Presentations" package: Needs["Presentations`Master`"] Draw2D[{ (* Draw the polar curve *) Directive[Thick,Brown], PolarDraw[Cos[5\[Theta]],{\[Theta],0,2\[Pi]}], (* Draw the polar grid *) Directive[Thin,Legacy@DimGray], ComplexCircle[0,#/8]&/@Range[8], ComplexLine[{0,ComplexPolar[1,# Pi/6]}]&/@Range[0,12] }, Background->LightBlue] Galaxia wrote: > The PolarPlot of Mathematica gives still the X-Y axes coordinate.
