RE: Plotting unfilled bars in GeneralizedBarChart

John,

Here is one method. Skip the Graphics`Graphics` routine and define your own
bars. Then draw them using Epilog in a FilledPlot. You need to give an
explicit PlotRange because PlotRange -> All does not seem to properly
account for items in Epilog. In Epilog, the bar function is Applied to all
of the data points.

Needs["Graphics`Colors`"]
Needs["Graphics`FilledPlot`"]

bar[x_, value_, width_] :=
    With[{w = width/2},
      Line[{{x - w, 0}, {x + w, 0}, {x + w, value}, {x - w, value}, {x - w,
            0}}]];

bardata = Table[{x, x^2/30}, {x, 10}];

FilledPlot[Sin[x], {x, 0, 10}, Fills -> Salmon,
   Epilog -> ((bar[#1, #2, 3/4] & ) @@ #1 & ) /@
     bardata, PlotRange -> {{0, 11}, {-1, 3.5}}];
