Sorry if I already missed a post where you said you couldn't (have had the flu), but could you use one of the various modules in CPAN to control gnuplot instead of trying to manipulate it yourself?
A quick search: http://search.cpan.org/search?query=Gnuplot&mode=all http://search.cpan.org/author/CAIDAPERL/Chart-Graph-2.0/Graph/Gnuplot.pm http://search.cpan.org/author/ILYAZ/Term-Gnuplot-0.5704/Gnuplot.pm Just a thought..... http://danconia.org -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
