Hello again,
I have two comments.

I also found this problem in my ubuntu, but only when I rendered the eps
file with evince, which is the default document viewer; openning the
same file with ghostview I see the discrete version.
Please, read this thread in the gnuplot news group for details:
http://groups.google.com/group/comp.graphics.apps.gnuplot/browse_thread/thread/de359b20cdc8092d
So, the problem was in the viewer and the generated eps file is correct.
And the same is true with the coloured version.

Are you writing your manual in latex? If you have problems rendering the
correct result, try to convert the eps graphics into pdf and then build
a pdf document:
$ epstopdf yourgraphic.eps
$ pdflatex yourwork.tex
Just guessing, I have not tested this.
Good luck.
