From: Michael A. Gilchrist on 19 Jun 2010 07:50 Hello, I'm working with some discrete probability functions and plotting them using ListPlot. Given the nature of the function, I believe its clearest to represent the values using bars rather than points. I know there's a BarChart function, but it isn't as easy to use (e.g. you can't just give it a list of x, y coordinates and you can't easily have overlaying datasets, they sit next to each other). I'm wondering if anyone else has run into this problem and/or has any suggestions on how to solve it. For example, are there options I can set that will give me the desired behavior? Thanks for your time in this matter, Sincerely, Mike
From: Sjoerd C. de Vries on 20 Jun 2010 03:44 Michael, How about this: ListPlot[Prime[Range[25]], Filling -> Axis, FillingStyle -> {Thickness[0.03]}, ImageSize -> 500, Axes -> None, Frame -> True] Not a beauty, but it does what you ask for.

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]
From: Michael A. Gilchrist on 20 Jun 2010 03:45 Hi Michael, Thanks to you and the others who've responed. That was almost exactly the type of solution I was looking for. I'm left with one question and that is, "How do I get the colors to automatically parallel the colors being used for the symbols?" I suspect one can do this with a function command embedded within the FillingStyle-> option, but I've always found the syntax for such things trick. Thanks again for pointing out this simple solution and any help with this latter request would be appreciated.

I am not sure what effect you are trying to achieve, but you may find this technique useful. The particular options on which I am relying are Filling -> Axis, FillingStyle -> {{Red, AbsoluteThickness[5]}, {Black, AbsoluteThickness[10]}}, which creates the appearance of a bar chart where bars above the axis are thicker and black, bars below the axis are thinner and red. > > Good luck, > > Michael Stern > Merrin Capital Management > > > On Jun 19, 2010, at 7:46 AM, Michael A.
