# Apparently, HERE COMES THE PROBLEM: GNUPLOT doesn't bear a "here document" like
# this *inside a do-loop* (once you remove either one, everything goes fine).
#-GRANTED, IT'S NOT NECESSARY FOR THE CURRENT SCRIPT, BUT I'LL NEED IT FOR A FURTHER DEVELOPMENT-:
# Use a coarser grid when generating labels
# use a dummy definition g = $smallgrid() to force a single execution of a function that resets the grid parameters
function $smallgrid() << EOF

}
}
If I remove the do loop, it works perfectly (just for one loop value, of course). If I keep the do-for loop even for just one value, I've got that error message.
As you already mentioned, apparently, the (dummy)function definition within the loop is the problem.
Just for completeness and future reference, since you already suspected the function definition to cause the error, the following would have been a minimized example to reproduce the error:
reset session
do for [i=1:2] {
function $smallgrid() <<EOF
set dgrid3d 65,65 qnorm 9
EOF
plot x
}
Apparently, you cannot redefine a function within a loop. And in your case there is actually no need to define it within the loop, because nothing in the definition is changed. However, unlike undef for datablocks, there seems to be no undef for function blocks.
So, simply take it out of the loop, then at least I don't get the error message anymore. But from the strange output from your script and data, I cannot tell whether the output is really correct.
Try something like:
### this requires gnuplot>=6.0.0, because of functions blocks
reset session
function $smallgrid() <<EOF
set dgrid3d 65,65 qnorm 9
EOF
# many settings, etc.
# your loops
do for [i=1:3] {
do for [j=1:3] {
# some more settings
A = $smallgrid() # apply the settings in your function
# plot whatever you need
}
}
