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.
