<> I think that working with the relabel option is your best bet. You can automate the creation of the relabel() expression with a loop, but normally I'd suggest building it in a local macro , but I couldn't get the local to store the double quotes for use in the relabel option. Here's some examples of things I tried: ***! sysuse auto, clear forval n = 1/`=_N' { loc la1 `la1' `"`n' " " "' loc la2 `la2' "`n' " " " loc la3 `la3' `n' `" "' loc la4 `"`la4' `n' " "'"' } forval n = 1/4 { di in y as smcl "`n' {hline}" di in g "`la`n''" } ***! Anyone have an idea of how to store the double quotes in a local to pass to the relabel option? Since using the local didn't work for me, here's a less straightforward solution using a couple of string variables (which are limited to 244 chars) to do essentially the same thing: ***********! sysuse auto, clear foreach v in "1/15" "16/30" "31/45" "46/60" "61/74" { **get variable name** loc varname `v' loc varname: subinstr local varname `"/"' "", all **create "o" vars with relabel option** g o`varname' = "" forval n = `v' { if !inlist(`n', 1, 20, 40, 60 , 74) /// replace o`varname' = o`varname' + `" `n' " " "' if inlist(`n', 1, 20, 40, 60 , 74) /// replace o`varname' = o`varname' + `" `n' "`=make[`n']' ""' } } ds o* //<-- Here's the new vars for relabel() graph hbar (asis) price, bargap(10) /// over(make, relabel(`=o115' /// `=o1630' `=o3145' `=o4660' `=o6174') /// label(angle(horizontal) labsize(vsmall) labgap(5))) ***********! After kludging all this together, it might be more work than typing out the relabel() for 74 obs in the auto.dta; however, it would be useful for much larger datasets. (However, you can't get too much larger before the bars become indistinguishable.) - Eric __ Eric A.
