Patrice,
I am not really sure, that it makes sense
to have an optional argument for the origin of loglines.
It is not common at least in Germany.
However, it is not easy to make it run, so I will
leave it by now. Feel free to change the code.

All psgraph environment with
\psgraph(x1,y1)(x2,y2){...}{...} work correct with
loglines.
