Hi Janh, When you say that you have "multiple data sets of unequal sample sizes" are you speaking of the same kind of data" For example are you speaking of data from a set of experiments where the variables measured are all the same and where when you graph them you expect the same x and y scales?
Or are you talking about essentilly independent data sets that it makes sense to graph in a grid ?
