The second graph requested in Eric`s initial post requires some
modification:


*******
sysuse auto, clear
contract rep78 foreign, percent(perc)
   *-----added
	qui sum perc
	local x = round(`r(min)', 10)
	local y = round(`r(max)', 10)+10
	local t 10
if `r(max)'>75 & !mi(`r(max)') {
		local t  25
	 }
	mylabels `x'(`t')`y', local(labels) myscale(@) suffix("%")
   *------
gen strpercent=string(perc, "%4.1fc")+ " %"    /*chg. to 1 dec place*/
twoway (bar perc rep78)  /* 
*/ (scatter perc rep78, mlabcolor(black) msymbol(none)  /* 
*/ mlabsize(medium) mlabel(strpercent)  /* 
*/ mlabposition(12)), by(foreign, legend(off)  note(""))  /* 
*/ yla(`labels')   // <-- changed to use local created by -mylabels-
*******

BTW Eric, is there a conceivable case that would require one to check for a
missing "r(max)"? Anyway, the instinct to check for missings whenever
"greater than" is employed is a healthy one :-)

Thanks, Martin.  
This is a great workaround for my situation (& it's much better than my idea
of tinkering with the .grec file output).

Yes I agree, hopefully Stata will implement a percentage format someday.

Just FYI for anyone else who needs something like this:  
I slightly modified Martin's example to use NJC's -mylabels- (from SSC &
referenced in the 2008 thread Martin referred me to)  so that I could easily
shift the yaxis with the range of the data in a way that makes sense for the
way I need to display results--so, something like:

*******begin
sysuse auto, clear
contract rep78, percent(perc)
   *-----added
	qui sum perc
	local x = round(`r(min)', 10)
	local y = round(`r(max)', 10)+10
	local t 10
	if `r(max)'>75 & !mi(`r(max)') {
		local t  25
	 }
	mylabels `x'(`t')`y', local(labels) myscale(@) suffix("%")
   *------
gen strpercent=string(perc, "%4.1fc")+ " %"    /*chg. to 1 dec place*/
twoway (bar perc rep78)  /* 
*/ (scatter perc rep78, mlabcolor(black) msymbol(none)  /* 
*/ mlabsize(medium) mlabel(strpercent)  /* 
*/ mlabposition(12)), legend(off)  /* 
*/ yla(`labels')   // <-- changed to use local created by -mylabels-
*******end
(note that the ylab changes from increasing by 10 to increasing by 25 if the
r(max) > 75)


Thanks again, 

Eric
