Hi All, I’m very new in the world of ruby and working on translating some octave scripts (since that is not available on all stations and the scripts do nothing very fancy). But I do need errorbars on my plots (which are for now saved as png’s). I looked into gruff for making the graphs but it does not seem to support errorbars. any hints to where I might look?

Farrel, Thanks for your pointer, it looks interresting (also because of the fact that the octave script uses this) but I would rather have the nice graphs (looks do count sometimes) of gruff… Kind regards, Gerald On Thu, 2006-11-16 at 20:09 +0900, Farrel L. wrote: > > Drienerlolaan 5 PO box 2662 – NCLR B.V.
