I chose -abdata- because it was the only -webuse- data I could find that contained plentiful data on several percentage variables, much like the ones I have in my own data. I also chose it because I thought that Nick Cox was suggesting to me that it might instructive to use such data so that all interested parties (at least, those who have -mylabels-!) could replicate the problem I was having for themselves (as you've very kindly done: thanks very much). That said, I should have -collapse-d the data before running the graphs. > 2. Why are you manually specifying the ylabel option when -mylabels- > will do it for you? Initially, I was doing that, and I'm not sure I could give a cogent, intelligent answer as to why I didn't do so there. Let's call it an oversight. > 3. In your ylabel option, should it not be: ylabel(1 "100" .75 ....) > not ylabel(.1 "100" .75 ....). Yes, it should, but that's settled by -ylabel(`label100'...)-, as you point out. > 4.

But notice that the y-axis labels are _still_ normalized to the 0-1 scale (do you get the same?), when they should be labelled from 0-100. I take very seriously Nick Cox's rejoinder that you get in Stata what you ask it to do, but I'm now running what everybody would now agree is the correct code, and I'm still not getting quite the desired output. I'm not sure what else I can say.
