OK, I'll go for it after I have my gnuplot script working...

Well, actually I have played a bit with setting variables inside gnuplot and trying to concatenate them.

I succeeded in concatenating *string* variables:

gnuplot> VAR='polti'.'-'.`date +%Y`
gnuplot> print VAR
polti-2009
gnuplot> VAR=VAR.'-'.`date +%m`
gnuplot> print VAR
polti-2009-11

I think playing with these sort of variable definitions, also will lead me to success... What do you think of this?

Thanks,
Flavio Boniforti
