Thank you all for your solutions. Of course I had been hoping for some
way to directly tweak FilledPlot itself to do this within the single
function. But it seems that's not possible.
The simplest solution seems to be of the form:
f[x_] := Sqrt[x]
Needs["Graphics`FilledPlot`"]
filled = FilledPlot[f[x], {x, 2, 10}, PlotRange -> {{0, 10}, All}];
graph = Plot[f[x], {x, 2, 10}, PlotRange -> All];
Show[{filled, graph}];
In such situations, I find it handy to use the functions DontShow and
DoShow from David Park's DrawGraphics package to more readably
manipulate DisplayFunction:
Needs["DrawGraphics`DrawingMaster`"]
filled = DontShow @ FilledPlot[f[x],{x,2,10},PlotRange->{{0,10},All}];
graph = DontShow @ Plot[f[x],{x,2,10},PlotRange->All];
DoShow[{filled, graph}];
Using Graphics`DisplayTogether` has the advantage that PlotRange does
not seem to be needed, at least for the examples I tried.
Needs["Graphics`Graphics`"]
filled = DontShow @ FilledPlot[f[x], {x, 2, 10}];
graph = DontShow @ Plot[f[x], {x, 0, 10}];
DisplayTogether[filled, graph];
