Instead of BarChart, I would use either DiscretePlot (when the distribution can be specified as a function) or ListPlot. For example, with DiscretePlot DiscretePlot[{PDF[BinomialDistribution[50, .8], k], PDF[BinomialDistribution[50, .3], k]}, {k, 0, 50}, Frame -> True] or with ListPlot ListPlot[{Table[PDF[BinomialDistribution[50, .8], k], {k, 0, 50}], Table[PDF[BinomialDistribution[50, .3], k], {k, 0, 50}]}, PlotStyle -> PointSize[.015], Filling -> Axis, FillingStyle -> Thickness[.002], Frame -> True]
