Try using the plain x11 terminal, and see if that works better?
Roland, perhaps you also know the origin of this gnuplot warning: Could not find/open font when opening font "arial", using internal non-scalable font >From searching the net it appears that gnuplot is not finding truetype fonts, something to do with GD library. I've got xorg-fonts-truetype-7.4 and gd-2.0.35_1,1 installed. So I'm not sure what the problem is. Several functions are not available without truetype fonts, e.g. label rotation, which is sometimes useful. many thanks anton -- Anton Shterenlikht Room 2.6, Queen's Building Mech Eng Dept Bristol University University Walk, Bristol BS8 1TR, UK Tel: +44 (0)117 331 5944 Fax: +44 (0)117 929 4423 _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
