The approach recommended by Roland Franzius works for your example: ParametricPlot[{Cos[x], Sin[x^2]}, {x, 0, Pi}] ListLinePlot[ Table[{Cos[x], Sin[x^2]}, {x, 0, Pi, Pi/64}], AspectRatio -> 1, Filling -> {1 -> {0, {White, LightBlue}}}] Bob Hanlon On Sat, Aug 31, 2013 at 8:15 AM, Francisco Gutierrez <fgutiers2002 at yahoo.com > wrote: > > Many thanks to Helen Read, Craig Carter, Murray Eisenberg, Roland > Franzius, Bob Hanlon, and other group members/gurus for their responses to > my query.
