Thanks. > You may write your own polar grid, e.g.: PolarGitter[r_, dr_, df_] := {Table[ Text[2 Pi n/(2 df), Through[{Re, Im}[(1.1 r) Exp[2 Pi I n/(2 df)]]]], {n, 0, 2 df - 1}], GrayLevel[0.6], Table[Line[{Through[{Re, Im}[r Exp[n I Pi/df]]], Through[{Re, Im}[-r Exp[n I Pi/df]]]}], {n, 0, df}], Table[Circle[{0, 0}, n r/dr], {n, 1, dr}] } Then: PolarPlot[E^(x/20), {x, 0, 35}, Prolog -> {PolarGitter[7, 1, 8]}, PlotRange -> {{-8, 8}, {-9, 9}}, Axes -> None] Gruss Peter -- ==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-== Peter Breitfeld, Bad Saulgau, Germany -- http://www.pBreitfeld.de
