Martin answered Michael's second question well, but my guess is that Michael did not mean what he said. I guess he wants a mean for each category, and extending Martin's solution to show several horizontal lines is not especially attractive. With -stripplot- from SSC you can combine a dot plot (sensu -dotplot-), display of boxes and display of means -- and indeed other possibilities. This sequence omits the experimentation needed in practice to get a good balance of elements. sysuse bplong, clear set scheme s1color egen mean = mean(bp), by(sex) gen sex2 = sex - 0.1 stripplot bp, over(sex) vertical box(barw(0.1)) stack /// boffset(-0.1) height(0.4) width(2) /// addplot(scatter mean sex2, ms(D) msize(*1.5)) Michael's first question about a second axis permits various answers, mine being that what he wants is not possible with -graph box- and not a good idea anyway. Create a second graph to show side by side with the first. Nick n.j.cox@durham.ac.uk Martin Weiss "Additionally, I'd like to add the mean to the boxplot.
