Any of you guys know of some software I can use as a replacement for Origin? Anyone have experience with Octave/GNUPlot? It seems nice so far, but I can't figure out how to do some things. And what if I want to mess with the placement of objects (e.g., legends) or add an arrow to a specific part of a curve or something? Command line is nice for a lot of stuff, but sometimes I just want a GUI...
Looks like I'm stuck with origin for the time being, which is a major PITA since it's unbelievably slow and locks-up or crashes fairly often. Not to mention I only have a copy on my work desktop, so I can't easily work from home (and doesn't run in linux...)
