is there a way to find out if gnuplot is complaining about something through Chart::Gnuplot ?
You could make a copy of the source code of Chart::Gnuplot and edit the code to check the return value of the call to system in sub _execute: 
if (system("$gnuplot $self->{_script}")) {
   die "Error: $gnuplot $self->{_script}: $?"
}
