On the occasion of this thread: Should the online documentation for -egen, fill()- not contain the sentence in [D] egen: "To produce repeating patterns, you present fill() with the pattern twice in the numlist"? That would have saved me a lot of rummaging through the Statalist archives :-)

In addition to Maarten`s excellent contribution, let me provide a final solution for Nikolaos via the -eclplot- package by Roger Newson. I think it pretty much does what he has wished for all along...

qui{
//create data
set obs 600
gen arm= cond(_n<301,0,1)
lab def arms 0 "control" 1 "experimental"
la val arm arms
egen float interval = fill(0 1 3 6 9 12 0 1 3 6 9 12)
egen float measurement = seq(), from(1) to(50) block(6)
//fictional value of measurement (no systematic diff btw control and experimental group)
gen mymeasurement=rchi2(3)
}
//check
mean mymeasurement, over(arm interval)
//collapse
collapse (mean) mean=mymeasurement (semean) semean=mymeasurement, by(arm interval)
gen lb= mean-invnormal(0.975)*semean
gen ub= mean+invnormal(0.975)*semean
//get -eclplot- by Roger Newson
cap ssc inst eclplot
//see what happened there...

eclplot mean lb ub interval, eplot(bar) ciopts(blcolor(black)) estopts(barwidth(0.25)) ///

What about this:
*---------------- begin example ---------------------
clear*
qui{
//create data
set obs 600
gen arm= cond(_n<301,0,1)
lab def arms 0 "control" 1 "experimental"
la val arm arms
egen float interval = fill(0 1 3 6 9 12 0 1 3 6 9 12)
egen float measurement = seq(), from(1) to(50) block(6)
//fictional value of measurement (no systematic diff btw control and experimental group)
gen mymeasurement=rchi2(3)
}
//check
mean mymeasurement, over(arm interval)
//collapse
collapse (mean) mean=mymeasurement (semean) semean=mymeasurement, by(arm interval)
gen lb= mean-invnormal(0.975)*semean
gen ub= mean+invnormal(0.975)*semean
gen interval2 = cond(arm == 1, interval + .25, interval - .25)
twoway bar mean interval2, barwidth(.4) || ///
rcap lb ub interval2, ///
xlabel(0 1 3 6 9 12) ///
xmlabel( -.25 "c" .25 "e" ///
.75 "c" 1.25 "e" ///
2.75 "c" 3.25 "e" ///

8.75 "c" 9.25 "e" ///
11.75 "c" 12.25 "e" ) ///

*------------------- end example -------------------
Hope this helps,
