The following may do what you want
In:= r = 0; list1 = Table[r += Random[Integer, 20], {60}]; In:= r
= 0; list2 = Table[r += Random[Integer, 25], {80}]; In:= r = 0; list3
= Table[r += Random[Integer, 15], {100}]; In:= pl1 = Show[ListPlot[
list1], ListPlot[list2], ListPlot[list3]]; In:= pr = PlotRange /.
FullOptions[pl1] Out=
{{-2.5, 102.5}, {-25.7, 1053.7}} In:= Show[
pl1, Plot[.1x^2, {x, pr[[1, 1]], pr[[1, 2]]}], PlotRange -> pr];
