Nick,
Thank you for your enlightening reply. My problem was that the number
74.90000000000001 was drawn in a graph, instead of 74.9. Converting
the variable to a string is the solution I needed. I also appreciate
the style advice, I was not aware of the illegal syntax and I had not
considered that I could use the values returned by -summarize- to
create macros.
With your help I could reduce my data set from
sex rg5 order tmax mmax fmax
Male 72.2 2 74.9 72.2 74.9
Female 74.9 1 74.9 72.2 74.9
to
sex rg5 order
Male 72.2 2
Female 74.9 1
"Male" and "Female" are labels for the actual values 1 and 2. My
original (and incorrect) commands for producing a bar graph were:
#delimit ;
local textpos1 = tmax/100*20;
local textpos2 = tmax/100*50;
local mvalue = round(mmax,.1);
local fvalue = round(fmax,.1);
graph bar rg5,
over(sex, sort(order) gap(0) axis(off))
bar(1, bcolor(0 153 255) blcolor(white))
yscale(r(0 `max(tmax)') off) ylabel(minmax, nogrid)
outergap(0) plotr(m(zero))
graphregion(color(white) margin(zero))
text(`textpos1' 25 "Girls", size(20) color(white))
text(`textpos1' 75 "Boys", size(20) color(white))
text(`textpos2' 25 "`fvalue'%", size(20) color(white))
text(`textpos2' 75 "`mvalue'%", size(20) color(white))
legend(off);
The revised commands are:
#delimit ;
sum rg5;
local scalemax = r(max);
local textpos1 = r(max)/100*20;
local textpos2 = r(max)/100*50;
sum rg5 if sex==1;
local mvalue = string(r(max), "%2.1f");
sum rg5 if sex==2;
local fvalue = string(r(max), "%2.1f");
graph bar rg5,
over(sex, sort(order) gap(0) axis(off))
bar(1, bcolor(0 153 255) blcolor(white))
yscale(r(0 `scalemax') off) ylabel(minmax, nogrid)
outergap(0) plotr(m(zero))
graphregion(color(white) margin(zero))
text(`textpos1' 25 "Girls", size(20) color(white))
text(`textpos1' 75 "Boys", size(20) color(white))
text(`textpos2' 25 "`fvalue'%", size(20) color(white))
text(`textpos2' 75 "`mvalue'%", size(20) color(white))
legend(off);
Thanks again, this was a most instructive excercise.
