Re: [OT] gnuplot quality (was Re: [Orgmode] org-plot file export options)
Tried this and it works well -- the output is definitely much better! One oddity -- the EPS generated is black and white whereas the typical output was in color... silly option I'm missing?

Much appreciated. Color works perfectly.

Thanks for both tips -- I'll give these a try on Monday when I'm back at work. Much appreciated!
