Sorry I had to copy it by manual typing. Now I copy/pasted it:

 \psset{yunit=100cm}
 \begin{pspicture}(-0.5,-1.1)(11,-1.6)%
   \psaxes[dy=1cm,Dy=0.01,Oy=-1.10]{->}(0,-1.10)(11,-1.6)
   \psdots(1,-1.577)
   \psdots(2,-1.526)
   \psdots(3,-1.475)
   \psdots(4,-1.423)
   \psdots(5,-1.373)
   \psdots(6,-1.321)
   \psdots(7,-1.270)
   \psdots(8,-1.217)
   \psdots(9,-1.170)
   \psdots(10,-1.118)
 \end{pspicture}

As you can see the diagram is too large. But when I change  
\psset{yunit=100cm} to  \psset{yunit=45cm} the y-values do not 
correspond to the psdots I declared.
e.g. the highest point is at 1.315 and not at 1.577.

I do not understand why.

With your given example it works but I do not understand why scaling the 
diagram totally screws up the y-values

thanks

Nicolai
