Hi, you can't replace the Point[] primitive in ListPlot[] by the prolog option. You can hook Point[] with Block[{Point}, Point[a_] := Text["\[EmptyCircle]", a]; ListPlot[data] ] or replace it later gr = ListPlot[data, DisplayFunction -> Identity] /. Point[a_] :> Text["\[EmptyCircle]", a]; Show[gr, DisplayFunction -> $DisplayFunction] You can use the Prolog in Plot[] Plot[Sin[x],{x,0,2Pi},Prolog->{Text["\[EmptyCircle]", #] & /data}] Regards Jens David Robinson wrote: > > Excuse a question from a beginner. > > There has been some discussion about using graphics primatives to show > symbols on plots.
