When performing histograms the data set to be included into each bin at the bin edges is not an option that can be set by the end user. If for example, I am graphing test results against a limit and the limit line is on bin edge, the user should be able to select whether the upper or lower limit are included in the bin. I.E bins are 1, 1,5, 2, 2,5, 3, limit line is 2.0. If limit is X > 2.0 then a value 2.0 is a fail so it should fall into the 1.5 -2.0 bin . If the limit X >= 2.0 then a value of 2.0 it is a pass and should fall into the 2.0 - 2.5 bin. Currently the option is not there and you are left with data points being forced into the wrong bins which displays the intended data set improperly.
