" The only way -sum- should report a missing r(max) is if all the data in
the variable were missing"



I am not sure about that. It would appear from the example that "r(max)" is
not returned at all in this case:


*******
clear*

set obs 100
gen x=.
ins x
su x
ret li

if mi(`r(max)') {
	di in r "MISSING!!!"
} 
else{
	di in r "NOT MISSING!!!"
}

*******

No, it's just habit.  The only way -sum- should report a missing r(max) is
if all the data in the variable were missing--which wouldn't lend its self
to a useful graph.  

Thanks for updating this to address my second example.  In applying this to
my real data, I used -graph combine- but this is faster than waiting on
-graph combine-.  Also, there is an advantage in using the "by" option, in
lieu of -graph combine-, in that it leaves out the extra set of yaxis
labels, which looks much nicer, and it places the "by" group labels at the
top of the graphs automatically.  

Best,

Eric
