I am not sure why this didn't work. Using the auto data set, the comparable commands would be twoway (scatter mpg weight if fore == 0) /// (qfit mpg weight if fore == 0) /// (scatter mpg weight if fore == 1 ) /// (qfit mpg weight if fore == 1) which works fine for me. However, like your example, this returns an error: twoway (scatter mpg weight if fore == 0 || qfit mpg weight if fore == 0) /// (scatter mpg weight if fore == 1 || qfit mpg weight if fore == 1) 0| invalid name invalid syntax r(198); Though if we do just one set of -twoway (scatter...|| qfit...)- it works. Again, I think the problem binding () and separating ||. Either notation works, but combining doesn't seem like a good idea. When it gets to capture -noi .Graph : .twowaygraph_g.new- (-set trace on- for all the details) it appears the outer set of parentheses is stripped. So twoway (scatter mpg weight if fore == 0 || qfit mpg weight if fore == 0) becomes essentially -twoway scatter... || qfit...- : = capture noi .Graph : .twowaygraph_g.new scatter mpg weight if fore == 0 || qfit mpg weight if fore == 0 In this syntax: twoway (scatter mpg weight if fore == 0 || qfit mpg weight if fore == 0) /// (scatter mpg weight if fore == 1 || qfit mpg weight if fore == 1) there are no outer parentheses = capture noi .Graph : .twowaygraph_g.new (scatter mpg weight if fore == 0 || qfit mpg weight if fore == 0) (scatter mpg weight if fore == 1 || qfit mpg weight if fore == 1) 0| invalid name And so it is views each ( ) as one command. Of course, none of the above may be correct, but it is how I read the log file. The moral seems to be don't try to bind() what should be separated|| Scott > -----Original Message----- > From: owner-statalist@hsphsun2.harvard.edu [mailto:owner- > statalist@hsphsun2.harvard.edu] On Behalf Of Branko Milanovic > Sent: Thursday, February 10, 2005 3:35 PM > To: statalist@hsphsun2.harvard.edu > Subject: RE: st: Superimposing graphs > > > Scott, > > Unfortunately, it does not work.
