Hi.

I'd like to plot a ParametricPlot graphic image. It's easy, but I'd like
also to color the curve obtained according to a gradient (Hue, for
example), so the line changes color according the parameter value. In this
case if the coordinates are {t Sin[t], t Cos[t]} the point at t=value will
be colored as Hue[value]. There's a way to do this, instead to have a line
with a costant color defined by StylePlot?

I've obtained this in a ParametricPlot3D, using
{x[u,v],y[u,v],z[u,v],{SurfaceColor[Hue[f[u,v]]]}} (thanks to Davin Park
example in a my previous post about ellipsoid), but this does not works in
2D case (there's no surfaces...)

Thanks for answers

Daniele
