Hi again!
I found the problem with gnuplot and my code
by downgrading my gnuplot 4.0.0 to 3.7.2.
My colleague was using gnuplot 3.7.3 which
does not have
"unset key"
"unset xtris"
"unset ytris"
So, if I want my code to work on 3.7.x versions
of gnuplot, I must avoit "unset ...".
Nevetheless something equivalent must have been
possible also in gnuplot 3.7.x.
Does any of you by chance know how to unset the legend and
x/y coordinates in gnuplot 3.7.x?
