Here is some sample code that uses Manipulate with ListPlot v1 = Table[Random[], {50}]; v2 = Table[Random[], {50}]; fn[a_, b_] := a v1 + b v2 f[n_] := If[n >= 0, "+", "-"] Manipulate[ ListPlot[fn[a, b], Filling -> Axis, PlotRange -> {-.15, .15}, PlotMarkers -> {Automatic, Medium}, FillingStyle -> {Red, Green}], {{a, 0, "Param 1"}, -.1, .1, .01, Appearance -> "Labeled"}, {{b, 0, "Param 2"}, -.1, .1, .01, Appearance -> "Labeled"}] I would like to do things with the markers {color differently when positive, change to "+" when positive, use labels rather than "dots", ...} Is this possible? Are there some simple examples of this. Have not been able to find in the documentation. -- Richard Palmer Home 508 877-3862 Cell 508 982-7266
