The notebook below points to a solution.  Run it and then modify to suit.

Needs["Statistics`"];
Needs["Graphics`FilledPlot`"];
Clear[jpdf, m, f, x, y];
jpdf = PDF[NormalDistribution[2, 1], x];

f[y_] := (jpdf /. x -> y) /; 1 <= y <= 3
f[y_] := 0 /; y < 1 || y > 3

m[y_] := (jpdf /. x -> y) /; y < 1 || y > 3
m[y_] := 0 /; 1 <= y <= 3

SetOptions[FilledPlot, DisplayFunction -> Identity, 
Ticks -> {Range[-1, 6], None}, Axes -> {True, False}, 
Fills -> GrayLevel[0.7], PlotRange -> {0, f[2]}];

(* remember : FilledPlot shades region between curves *)

g = FilledPlot[{f[x], jpdf}, {x, -1, 6}]; 
h = FilledPlot[{m[x], jpdf}, {x, -1, 6}]; 

xlabel = TableForm[
Map[StyleForm[#, FontFamily -> "Arial", FontWeight -> "Bold", 
FontSize -> 12] &, {"Centered Line 1", "Centered Line 2"}], 
TableAlignments -> Center];

Show[GraphicsArray@{h, g}, Frame -> True, PlotLabel -> xlabel, 
ImageSize -> {300, 100}];
