While this seems like a useful option, it can rapidly result in
illegible graphs and crowded axis labels in the presence of groups of
widely differing sizes. JMP does it, and I keep the option turned off
by default.
If you want to give an idea of the amount of data in each group, then
superimposing this as text on the graph might be more efficient.
What always seemed to me to be a better idea was giving some sort of
display of the actual data points with a boxplot superimposed, or a
little to one side, as you can do with Nick Cox's -stripplot-. This
shows more and, of course, gives a good impression of the density of
data behind each boxplot.
