why just decrease the label size and/or change the angle of the label

试过了 还是不行呀

// Breaking up long labels

sysuse auto, clear

#delimit
label define origin 0 `"group0 group0 group0 group0 group0
group0 group0 group0 group0 group0"', modify;

label define origin 1 "group1 group1 group1 group1 group1
group1 group1 group1 group1 group1 ", modify;
#delimit cr


local relabels
local relabels1

levelsof for, local(groups)
  
local s_len=20  //Change to required length

foreach g of local groups {

  local label : label origin `g'
  local len : length local label

  if `len'>`s_len' {
        forvalues i=1/  `=`len'/`s_len'+1' {
            local p1 : piece `i' `s_len' of `"`label'"', nobreak
            local relabels `"`relabels' `=char(34)+ "`p1'" +char(34)' "'
        }

        local relabels1  `relabels1'   `=`g'+1'    `"`relabels'"'
local relabels
       
   }
}

graph hbar mpg, over(for, relabel(`relabels1' ))
exit





Breaking up long labels - with splitvallabels

Requires the user written command: splitvallabels
To download splitvallabels type the following on the Stata command line:
ssc install splitvallabels

sysuse auto, clear
   
label define rep78 1 "Very low rating in 1978" ///
2 "Mediocre - Low Rating in 1978"              ///
3 "Medium Rating in 1978"                      ///
4 "Not bad rating in 1978, considering"        ///
5 "Excellent in 1978--the best of the year!"
        
label values rep78 rep78
        
splitvallabels rep78 if rep78>=3, length(11) recode
        
graph bar mpg if rep78>=3, over(rep78, relabel(`r(relabel)') ) scheme(s1)

exit

可以试一下 altshrink 的option

请问有解决方法吗
