<font face="Myriad Pro">Many thanks Carsten and many thanks Herbert,<br>
<br>
concerning your version, Herbert, there is not only scaled the

When using<br>

<font face="Myriad Pro">the bar is as well scaled, which for sure makes
sense. Is it nevertheless possible to suppress the scaling of the
bar(s) -- I would like to have ONLY the arrowhead definitions globally
for a large document. Your solution is fantastic for the given example
-- however i have a large amount of some other graphics with bars and
vectors and there it doesn't look too good with that thick bars.<br>
<br>
Any ideas?<br>
