st: looping over a series of line plots |

Dear statalisters, I have micro data on individuals and the following variables: different wage and income measures, working status (3 categories) and year I and would like to plot trends in all of those wage and income measures across occupations and produce simple line plots. Since I want to produce a whole series of similar plots, I was looking for a smart way to save on code but I got stuck. Here is what I do to produce a single graph (my question follows below the code): ******* BEGIN OF CODE collapse wage, by(year occ); g wageocc1=wage if occ==1; g wageocc2=wage if occ==2; g wageocc3=wage if occ==3; collapse (sum) wageocc*, by(year); list; twoway line wageocc* year, xtitle("Year") ytitle("Hourly Wage") title("Hourly Wage by type of occupation") legend(label (1 "Employees") (2 "Self-Employed") (3 "Not employed"); ******* END OF CODE My question is how I might automatize a whole series of graphs. Here is what I thought I could do: +++++++++++ foreach var in varlist { collapse `varname', by(year occ); ... ... twoway line `varname'occ* year, xtitle("Year") ytitle(-variable label-) <<------- Here I would like to have the variable label of that variable which I currently loop about title(-variable label-"type of occupation") <<------- Here I would like to have the variable label of that variable which I currently looped about legend(label (1 "Employees") (2 "Self-Employed") (3 "Not employed"); <<------- Here I would like to have the VALUE labels of the working status/occupation variable, so something like -legend (label occlabel)- } +++++++++++ However, it seems that I do not get this to work the way I want: e.g. the -legend- option only allows to change labels one by one, so it does not seem to be possible to attach pre-defined labels. Any suggestions if there is a work-around? Best regards, Sascha Becker -- Dr. Sascha O.
