-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.
