st: Twoway-graph appears different in version 11 and version 12

[Dirk Enzmann <dirk.enzmann@uni-hamburg.de>]

I can't find the reason why the following -twoway- syntax produces 
graphs that look vastly different in Stata 12 as opposed to Stata 11 (in 
Stata 11.2 it appears as intended whereas in Stata 12.1 it does not).

Note: If you run the complete demonstration below, two files (graphs 
created by my own Stata versions 11.2 and 12.1) will be copied into your 
temp-directory and erased afterwards (but it will not overwrite files 
that exist already) - I hope the longer line containing 
"title("Verhaltensprobleme ..." will not get broken in the email sent:

* --- Start Stata demonstration ----

global testurl = "http://www.ottersbek.de/Stata/";

* Copy demo .gph-files into tempdir:
local pwdir = c(pwd)
local tmpdir = c(tmpdir)
cd "`tmpdir'"
copy "${testurl}L11_version11.gph" "L11_version11.gph"
copy "${testurl}L11_version12.gph" "L11_version12.gph"
cd "`pwdir'"

/* Graph created with Stata version 11.2
  (Stata/SE 11.2 for Windows (32-bit) Born 16 Feb 2012): */
graph use "`tmpdir'/L11_version11.gph", name("L11_version11", replace)
/* Graph created with Stata version 12.1
  (Stata/SE 12.1 for Windows (64-bit x86-64) Revision 20 Jun 2012): */
graph use "`tmpdir'/L11_version12.gph", name("L11_version12", replace)

* Erase demo .gph-files:
local tmpdir = c(tmpdir)
erase "`tmpdir'/L11_version11.gph"
erase "`tmpdir'/L11_version12.gph"

* --- End Stata demonstration ----
