Re: st: RE: graph combine & single legend

No; I didn't say that. My few experiments imply that with a -by()-
option you only get part of the way with -grc1leg- and have to clean
up afterwards, but I am not the author and have not used the program
much, so you must look elsewhere for a more conVincing answer.
