-mylabels- is a user-written program from SSC. I can reproduce something like this result some but not all of the time. I think the problem lies in your -twoway- call. I'd omit the parentheses in twoway (connected slavepr year if year<=1860) and I think the problem will go away, but I'm not sure why that is. Nick n.j.cox@durham.ac.uk John D.
