Labelling each curve and changing grid in ParametricPlot
Posted: Feb 2, 2013 1:15 AM

Hello

I wonder whether someone out there could help me with the following problem.

plot[\[Tau]_, \[CapitalOmega]_] := Module[{arg, abs},
{arg, abs} = Factor[Together[ComplexExpand[
Through[{Arg, Abs}[(1 + I*2*\[CapitalOmega])/(1 + I*2*\[Tau]*\[CapitalOmega])]]]]];
{arg/Degree, 20*Log10[abs]}]

ParametricPlot[Table[plot[\[Tau], \[CapitalOmega]], {\[Tau], {7, 8, 9, 10, 11, 12, 13, 14, 15}}],
{\[CapitalOmega], -0.5, -0.01}, AspectRatio -> 1, GridLines -> Automatic,
GridLinesStyle -> Dashed, ImageSize -> Large]

I need to label each curve with the value of tau and, instead of the normal grid, a grid based on the values of Omega.

I saw something related to the label problem on the net but could not figure out how to change it to my case. Something with Epilog.

Many thanks

Ed
