My advice to Faye is that titles like "1990", "1991" are fine. Adding "For year" repeatedly just adds busy detail without adding information. But, that aside, in terms of how you would best do it in Stata, I agree with Richard. The key is that the -by:- part looks at the value labels if they exist and the values if they don't. So, arrange some suitable labels in advance. (This is cleaner than using -graph combine-.) Here is a systematic way to do it. 1. Leave the -by()- variable exactly as is, but clone it: clonevar year2 = year 2. Define the labels: levelsof year2, local(years) foreach y of local years { label define year2 `y' "for year `y'", add } label val year2 year2 3. Now do your graph using -by(year2)-. Nick n.j.cox@durham.ac.uk Richard Ochmann alternatively to Martin's approach you could write your titles of the subgraphs in the value labels of the by-variable: sysuse auto, clear gen year = cond(runiform()<0.3,1978, cond(runiform()<0.6,1979,1980)) label define yearlab 1978 "For year 1978" 1979 "For year 1979" 1980 "For year 1980", modify label values year yearlab histogram price, by(year, note("")) "F. Gao" <gaofaye@gmail.com> I am trying to get a histogram by year. I use the following command hist y, by(year,graphregion(color(white))) freq 2. I would like to add a small title under each graph for each year, such as "For year 1990", "For year 1991", so that I could replace the title added by stata automatically on the top of each graph, like "1990", "1991". * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
