Any Mac users out there intrested in playing with some software for plotting graphs like the ones I posted a few days ago? I've been playing with the software, and it's in a state where its now in a relativly usable form. It's still a bit rough in places (and could do with more data being loaded into it!), but it's starting to be fun to play with.
If you're interested, then PM me and I'll send you out a beta copy.
