You can use -local macname : piece ..- to break up long variable
labels.
The example below breaks the label into lines approximately 30
characters in length.
sysuse auto, clear
label var mpg "Supercalifragilisticexpialidocious! This is a very very
long variable label"
foreach var of varlist mpg head {
local varlab: variable label `var'
local l = length("`varlab'")
local b = ceil(`l'/30)
if `l' > 30 {
forv i = 1/`b' {
local lab`i': piece `i' 30 of "`varlab'", nobreak
local varlab2 "`varlab2' "`"`lab`i''"'" "
}
}
else {
local varlab2 "`varlab'"
}
scatter price `var', caption("`varlab2'") xtitle(date) name(gr_`var',
replace)
}
