Dear Nick, You are right, thanks for your remark I have a panel database that I aggregate using the -collapse function. First of all, I generate a dummy variable that I would like to study (DUM) - gen DUM=variable_of_interest==1 then I collapse the database by week and type of individuals (2 types, identified by the dummy variable TYPE) -collapse (count) count_Y=Y /// (mean) mean_Y=Y /// (mean) mean_DUM=DUM /// , by(week type) fast I create the first graph, which requires at leat 10 datapoints per week and plots the evolution of the DUM's proportion for type 1 individuals - line mean_DUM week if count_Y>10&`TYPE'==1 , scheme(lean1) name(choice, replace) sort And I would like to plot it against the output Y for the two different types : -twoway (line mean_Y week if count_Y>10&`TYPE'==1,sort lcolor(black)) (line mean_Y week if count_Y>10&`TYPE'==0,sort lcolor(red)) , scheme(lean1) name(graph, replace) legend(off) Therefore I type : -graph combine choice graph, cols(1) xcommon The graph that I obtain is exactly what I want (one graph per row)... except for the (important) fact that there is a slight lag in the alignment of the x-axis due to (I guess) the difference in length of digits between DUM (0.2 for example) and Y (0.002 for example) ... What do you think ? Many, many thanks in advance, On 12 February 2012 15:13, Nick Cox <njcoxstata@gmail.com> wrote: > The thread you cite from 2003 concerns graphs from -graph hbar-.
