[pstricks] Error bars and pstScalePoints

[Martin Buchmann]

Hi all,

I am still struggling with pstScalePoints and my error bars and I know 
far to little to understand what is going on here.

I have checked the source of pstricks-add.tex to see how pstScalePoints 
works with the listplot macro but I don't really get it :-)
Is there a way to make \errorLine work with that? I know that I can 
simply use (x|y)unit for the scaling but I need the third and forth 
operator to add a fix value to all my data.

Any help is appreciated
   Martin
