The command -lgraph- that I wrote is for exactly this kind of problem if you don't want to create all the variables before plotting a graph. You can see it by typing: ssc des lgraph Tim -----Original Message----- From: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] On Behalf Of Donald Spady Sent: 28 March 2014 08:59 To: Statalist Statalist Subject: Re: st: graphing median values against time Nick It works.
