RE: st: adding info to bar graph

["Buzz Burhans" <buzzb3@verizon.net>]

Nick,

Thanks for your explanation.  I feel a bit better that I was not alone in
missing how the "5" functioned.  You were right that I didn't quite see how
the recursive use of the macro was being used, as I noted to Scott.

Thanks

Buzz

"5" looks like a typo: delete it. Otherwise the important idea is that
each time around the loop
you append a level and the text for that level, here a ratio spelled out
as numerator/denominator. 

In general, 

local macname `macname' <stuff> 

appends <stuff> to local macro macname.

Scott, 
I liked your solution for Rich's question; could you help me follow what
it
does with the local macro mytext?  I am having a hard time following how
Stata parses and processes this line of your program in the loop:

local mytext "`mytext' 5 `l'   "`n'/`d'"  "

Something like this?

sysuse auto,clear
levelsof rep, local(levels)
foreach l of local levels {
	qui count  if fore == 1 & rep == `l'
	local n = r(N)
	qui count if  rep == `l'
	local d = r(N)
	local mytext "`mytext' 5 `l'   "`n'/`d'"  "
}
egen percent = mean(100 * foreign), by(rep78)
egen total = sum(1), by(rep78)

twoway bar percent rep78,barw(0.5) text(`mytext', box bc(white)  )
ylabel(,angle(h)) ytitle(Percent Foreign)
