Austin, thanks for your reply. The reason I am trying to avoid 
-graph combine- is that almost never looks nice whenever the axis 
labels/titles aren't equally wide. In this case I am trying to 
reproduce this graph: ,
 so no y-labels in the second graph. You can tweak it by using the 
-fxsize()- option, but is quite fragile (you'll have to re-tweak the 
graph whenever you change the y-labels or whenever you use a 
different font). This is undesirable since this is intended as a 
code example that others might be able to use on their own data. The 
-by()- option automatically takes care of this problem, as can be 
seen in the example below. 

*--------- begin example --------
sysuse auto, clear
scatter pri mpg if for==0, /*
 */ name(dom, replace)
scatter pri mpg if for==1, /*
 */ name(for, replace)     /*
 */ ylab(none) ytitle("")

graph combine dom for,     /*
 */ ycommon xcommon        /*
 */ name("combined", replace)

scatter pri mpg, by(for)

*------- end example ------------
