Summary: Non-negative numbers are displayed too right in plots

Initial Comment:
I've noticed in maxima plots (based on postcript with gnuplot) that the positive numbers are slightly right-shifted from their axis ticks marks. I include a figure, see numbers 0, 1, 2 and 3 in the x axis of plot2d(sin(x),[x,-3,3])

Using epslatex I've found the reason, see the space in the output of non-negative the axis marks labels:

      \put(946,704){\makebox(0,0)[r]{\strut{}-1}}%
      \put(946,1111){\makebox(0,0)[r]{\strut{}-0.8}}%
      \put(946,1518){\makebox(0,0)[r]{\strut{}-0.6}}%
      \put(946,1925){\makebox(0,0)[r]{\strut{}-0.4}}%
      \put(946,2332){\makebox(0,0)[r]{\strut{}-0.2}}%
      \put(946,2740){\makebox(0,0)[r]{\strut{} 0}}%
      \put(946,3147){\makebox(0,0)[r]{\strut{} 0.2}}%
      \put(946,3554){\makebox(0,0)[r]{\strut{} 0.4}}%
      \put(946,3961){\makebox(0,0)[r]{\strut{} 0.6}}%
      \put(946,4368){\makebox(0,0)[r]{\strut{} 0.8}}%
      \put(946,4775){\makebox(0,0)[r]{\strut{} 1}}%
      \put(1078,484){\makebox(0,0){\strut{}-3}}%
      \put(2032,484){\makebox(0,0){\strut{}-2}}%
      \put(2986,484){\makebox(0,0){\strut{}-1}}%
      \put(3941,484){\makebox(0,0){\strut{} 0}}%
      \put(4895,484){\makebox(0,0){\strut{} 1}}%
      \put(5849,484){\makebox(0,0){\strut{} 2}}%
      \put(6803,484){\makebox(0,0){\strut{} 3}}%

In the y axis the left space is not a problem, but in the x-axis the ticks must be

      \put(3941,484){\makebox(0,0){\strut{}0}}%
      \put(4895,484){\makebox(0,0){\strut{}1}}%
      \put(5849,484){\makebox(0,0){\strut{}2}}%
      \put(6803,484){\makebox(0,0){\strut{}3}}%

without the left space.

PD: It seems it's a postcript problem. png or gif figures seems to be fine
