Yep Sergiu, that sounds about right. My biggest need is a line graph, for which I need two values for each point (x, y), so there might be a couple parameters. But the general idea that you're outlining sounds exactly what I was thinking. And with the framework that Catalin already has, shouldn't be too hard to write.

I'll work on creating a patch for this and submit it; I am also excited about the 1.0 release, and so wouldn't ask you to divert resources to something new.

shawn.
