You are allowed to use -graph bar- yourself, of course:


*************
graph hbar (asis) sampled screened noreply, over(m) stack bar(1,
fcolor(green)) bar(2, fcolor(yellow)) bar(3, fcolor(red)) blabel(total)
legend(rows(1))
*************

You are -recast-ing to the -twoway- graph "bar", not the standalone -graph
bar-. If you drilled your way to the very bottom (think
http://www.stata.com/meeting/dcconf09/dc09_radyakin.pdf), you would find
that these two derive from the same substance, but the major demarcation
line for the end user still runs between the -twoway- graphs and the "rest
of world".

Those hyphens in your command need to be stripped off in any event, and the
double comma does have a special meaning which Nick elucidated in a post
some time in the past, but you may want to stick to one per Stata command
:-)

Martin, that makes sense, and this worked well for the color option,  
but I'm puzzled as to why
	-blabel(total)-
which is a legal option of -graph bar-, produces the error message
	option blabel() not allowed
with the following command:
	*******
	sc sampled screened noreply m,  xla(576/599,angle(90))  name(s,  
replace), fcolor(green yellow red) recast(bar) -blabel(total)-
	*******
