Pardon me, messing up the language policy.
This is a rough translation:

I assume the problem's origin in usage of psaxes and pspicture* 
simultaneously. This leads to a cut off lower boundary label. Since I 
encountered this effect also several times, I red (German) article 
"http://anamorphose.de/rechnen.pdf" on "LaTeX calculus".

My approach is to add 0.001 (psunits) to the lower boundaries values so 
the "lowest" label is omitted.
