Re: st: Re: Axis label

[Oliver Jones <ojones@wiwi.uni-bielefeld.de>]

Hi,

even so Nick already gave an solution, here is an example of how I would have done it (before 
seeing Nick's solution).
************* begin example *******************
clear
* Create some example variable
set obs 3
gen str5 parm = "a"
replace parm = "b" in 2
replace parm = "c" in 3
list
gen qvs = rnormal()

* Asuming the data are sorted the way you want them you can just
* create an id variable
gen int id = _n

* Make a label out of you string variable
levelsof parm
tokenize `"`r(levels)'"'
local i = 0
while "`1'" != "" {
	local i = `i' + 1
	dis `i'
	dis "`1'"
	label define lbl_parm `i' "`1'", modify
	macro shift	
}

* attach the label to your id variable
label values id lbl_parm

list

tw scatter qvs id, xlab(, valuelabel)

exit
************* end example *******************

Best
Oliver
