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 version 8.2 args gname qui graph describe `gname' window push `r(command)' end then I just type: grget mygraph.gph 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.
