Thanks to everyone is this thread, and to Nick, David and Scott for their solutions. It certainly was easy once you know how. I found Scott's solution easiest for me to use. My final code was: use raoadotplotdata,clear local i = 1 foreach var of varlist age - all { local l`var' : var label `var' local a " `a' `i' `"`l`var''"' " local ++i } collapse age-all, by(type) stack age-all, into(a) clear label def _stack `a' label val _stack _stack bys _s: gen origin = _n -1 reshape wide a, i(_s) j(origin) label var a0 "RA" label var a1 "OA" graph dot (asis) a* , ylab(.5 [.1] 1) exclude0 schem(bw) ytit(Concordance coefficient) xsize(4) ysize(5.3) over(_s) legend(position(3) ring(0)) Fred On Fri, Jun 11, 2010 at 12:18 PM, Nick Cox <n.j.cox@durham.ac.uk> wrote: > This information to me supports my earlier suggestion.
