The reason why you didn't get it to work because you fed the
-: label- extended macro function the variable name rather than
the name of the label. Quoting the helpfile:
returns the value label of # in valuelabelname. For instance,
label forlab 1 might return Foreign cars if forlab were the
name of a value label and 1 mapped to "Foreign cars".
So you can fix your program as follows:
*-------------- begin example ----------------
capture program drop km
program km
local h
local g 1
qui levelsof `1', local(lev)
local lab : value label `1'
foreach val of local lev {
local k `:label `lab' `val''
local m `m' lab(`g' "`k'")
local ++g
local gr `"`gr' scatter price mpg if `1' == `val' ||"'
}
twoway `gr', legend(`m')
end
sysuse auto, clear
km foreign
*---------------------- end example ------------------
