Re: st: RE: added graph feature: solution??
I found that -graph describe- also provide a lot of info about a saved graph
through -return list-. I wrote up a short ado a while ago that grabs the
graph command from a saved graph file and puts it in the review window so
that I can click on it and edit it in future sessions. I still need to use
the right dta file to make any edits work, but that's not too hard (and
typing -ret li- will tell me what file I was using).
program define grget
qui graph describe `gname'
window push `r(command)'
then I just type:
This approach won't solve the problem with higher level graph commands that
use tempvars, like Kaplan-Meier graphs, because those variables no longer
exist once the graph is rendered -- although their values are stored in
sersets in the gph file.
