histograms of identical distribution is different. maybe binnumber is the problem?

i found the code attached below in the archives. it will display two histograms without shading in one graph. note both histograms are generated exactly the same way using exactly the same number of sample points. for me, at least, it will show a pattern of a few of the distributions having a lower number of points about the mean. what causes this? I think it has to do with the way histograms are made? is there a way to control bin width or number in a convenient way? like.. binwidth-> (numberof points)/(whatever bin number you want to use) Do[ normdata = RandomArray[NormalDistribution[], 10000]; h1 = Histogram[normdata, BarEdgeStyle -> Hue[0], BarStyle -> {}, DisplayFunction -> Identity]; normdata2 = RandomArray[NormalDistribution[], 10000]; h2 = Histogram[normdata2, BarStyle -> {}, DisplayFunction -> Identity]; DisplayTogether[h1, h2], {i, 10}] __________________________________ Do you Yahoo!?
