psgraph does nothing else then calculating the two units
depending to your logical coordinates and the physical width.
With setting the coordinates for psaxes as you like,
everything should be possible.

On the other hand, if you have easy coordinates,
like integers, then calculating the x|y-units is
easy and there is no real need for \psgraph

yes, that is true. I fixed it (hopefully) in

you are welcome
