Dear Nick (and others), Thank you for the hint but unfortunately I have not been able to see how this solves the problem. Reshaping the data as you suggest is not a problem, but I still can't see how to connect the scatterplot points with lines in the specific way needed. Perhaps you (or someone else) could give a further clue, or elaborate some of the other various approaches that you mention exist? Thanks for the help. regards, Gisella --- On Fri, 12/3/10, Nick Cox <n.j.cox@durham.ac.uk> wrote: > From: Nick Cox <n.j.cox@durham.ac.uk> > Subject: st: RE: complicated scatterplot with connected points > To: "'statalist@hsphsun2.harvard.edu'" <statalist@hsphsun2.harvard.edu> > Date: Friday, December 3, 2010, 5:44 PM > There are various approaches to this. > One is to restructure your data so that the graphics command > becomes easier. > > preserve > reshape long x y, i(city) > > Spelling is Stata. > > Nick > n.j.cox@durham.ac.uk > > > Gisella Young > > I want to draw a slightly complex scatterplot in STATA and > have not been able to find a way how.
