ok I see. This depends to the dy. In the current pstricks-add
the lines are by 0.2, 0.3, 0.4 ,0.5
But it is no problem to get the same behaviour.

I uploaded the 1.65 version, which has now two
additional options logDx=0.1 and logDy=0.1 which
define the step for the lines. You can change these
values in the usual way.
