Tia, The following gives what you want Show[Graphics[ ContourPlot[Cos[x] + Cos[y], {x, 0, 4 Pi}, {y, 0, 4 Pi}, ContourLabels -> Automatic, PlotPoints -> 100, Contours -> 5, Frame -> True, FrameStyle -> Directive[Thick], LabelStyle -> {18, FontFamily -> "Arial"}]], Graphics[{Red, PointSize[Large], Point[{{2, 2}, {4, 4}, {6, 6}, {8, 8}, {10, 10}}]}]] I just substituted the Cos[x]+ Cos[y] since I could not execute your StabilityFnlens[f1, f2]. The problem lies in the closing brackets for your first call of Graphics and ContourPlot. -Mike On Sat, Sep 6, 2008 at 2:08 AM, SeekUp <seek.up.girl at gmail.com> wrote: > I am trying to add Points to my ContourPlot to highlight certain points. > The > code below doesn't work.
