Postscript driver and gnuplot 4.0, I tried various fonts, but I need them
to have a certain size so that they are readable, which I guess makes things
worse (I can prevent them from overwriting each other by changing the xtics
increment, the problem with overwriting the axes, x and y, remains).

I understand that it may be non-trivial to to it automagically, what I
was hoping for was something like the xoff and yoff options to xlabel.
Of course ideally you would not have to adjust such things, but with such
options I could manually adjust the offsets so that they do not overwrite
the axes in 3d plots even if gnuplot did not guess correctly the font
height and width. I haven't found such an option but I guess that if
it has been implemented for xlabel, it should not be more difficult
to implement it for the axes numbers too. Actually, xlabel sometimes
has similar problems, but they are always fixable manually using xoff
and yoff.
So if such an option does not exist, I would like to submit a wishlist
item:) What syntax would be appropriate for such an option?
Thanks,
