Why store it? Just -summarize- immediately before drawing the graph, and
store the graph instead of the returned value. So your loop would be
***
foreach x of local lcountry {
sum gdp_growth_quarter if country==`"`x'"'
//then draw the graph and save it, based on r(min) and r(max)
}

Subject: Re: st: AW: RE: axis(1) and axis(2) scales in graphs
Thank you very much for your answers. I was thinking on one possible
solution to this problem. Making both sides symmetric. For example, if
the right hand axis ranges from -6 to 6 and the left hand axis ranges
from -25 to 25, then in both cases zero should be at the middle,
right? (see example)
****** begin example *************
clear*
set seed 123456
set obs 100
gen time=_n
gen serie1=rnormal()
gen serie2=rnormal(1,2)
tw ///
|| line serie1 time, yaxis(1) ///
|| line serie2 time, yaxis(2) ///
|| , yscale(range(-6 6) axis(1)) ///
yscale(range(-25 25) axis(2)) ///
yline(0)
****** end example *************
Well, the thing is that I am running the same graph for different
countries, so I would like to have different ranges for each country.
So I tried summarizing serie1 and serie2 for each country and saving
it into a local macro, so that I can latter put it on range. But for
some reason I had to use global macros (local macros disappeared after
the loop), and when trying to implement this code it doesn't work
properly (that is, I do not get the same results as in the previous
example.
Here I paste the code. crisis1 is just a d
********************beginning of code
*********************************************************
**** First loop creates the macros that are gonna be used in - range()
suboptions -
gen scountrystandard=subinstr(country," ","",.)
levelsof country, local(lcountry)
foreach x of local lcountry {
levelsof scountrystandard if country==`"`x'"',
local(lcountrystandard)
foreach y of local lcountrystandard {
levelsof date if crisis1==1 & country==`"`x'"'
qui sum gdp_growth_quarter if country==`"`x'"'
global lgdpmax`y' = r(max)
global lgdpmin`y' = -r(max)
qui sum diff_exchangerate if country==`"`x'"'
global ldiffmax`y' = r(max)
global ldiffmin`y' = -r(max)
}
}
**** Now I graph the stuff.
levelsof country, local(lcountry)
foreach x of local lcountry {
levelsof scountrystandard if country==`"`x'"',
local(lcountrystandard)
foreach y of local lcountrystandard {
levelsof date if crisis1==1 & country==`"`x'"'
#delimit ;
graph twoway
(bar gdp_growth_annual date, yaxis(1)
ysca(axis(1)
r(${=lgdpmax`y'} ${=lgdpmin`y'})) )
(line gdp_growth_quarter date, yaxis(1)
ysca(axis(1)
r(${=lgdpmax`y'} ${=lgdpmin`y'})) )
(line diff2_exchangerate date, yaxis(2)
ysca(axis(2)
r(${=ldiffmax`y'} ${=ldiffmin`y'})) )
(line diff_exchangerate date, yaxis(2)
ysca(axis(2)
r(${=ldiffmax`y'} ${=ldiffmin`y'})) )
if countryname==`"`x'"',
title(`x')
yline(0, axis(1) lstyle(foreground))
xline(`r(levels)', lwidth(vthin)
lcolor(gray) lpattern(shortdash))
saving(Graphs-test\crisis1`y', replace)
;
#delimit cr
}
}
***************** end of code ***********************************
Although you don't have the data, maybe somebody can give me a hint of
why Stata seems to be ignoring the -range suboptions-
Many thanks in advance!
