Needs["Graphics`Graphics`"];

xvalues = Range[0, 1, .05];

yvalues = 2*xvalues;

ticklabels = Range[0, 1, .1];

plot1 = BarChart[Transpose[{yvalues, xvalues}], 
      Ticks -> {Transpose[{(Length[xvalues] - 
                    1)*(ticklabels + (xvalues[[2]] - xvalues[[1]])), 
              ticklabels}], Automatic}, ImageSize -> {500, 310}];

plot2 = GeneralizedBarChart[
      Transpose[{xvalues, yvalues, 
          Table[xvalues[[2]] - xvalues[[1]], {Length[xvalues]}]}], 
      ImageSize -> {500, 310}];
