I'm not super experienced graphing with Stata so this is a somewhat basic question. I am making a simple bar graph that is something like graph bar (sum) dollars, over(product_type) over(cat_var). If my cat_var was, say, is_teenager with values of 0/1, would it be possible to use the over command to divide the graph so that it showed all values of 0/1 (corresponding to all observations) and just the values of 1(corresponding to teenagers) rather than the default split of 0 (not teenagers) and 1(teenagers)? Basically I want to section the graph by a subset grouping rather than a disjoint grouping and am wondering if you can do this with the over command or if there is a better approach. Thanks!
