I use GtkExtra for an in-house data display program. It works fine for my plots, tested up to ~10k points. It will do 200 points updated twice a second with no problem, running on a Sun (forget what, 450 MHz and boatloads of RAM) and displaying on NT PC's (800 MHz typically) running Hummingbird's X server. At 5 times a second it drops occasional updates (I poll for data from a timer, so if I fall behing I just miss a poll.) I use only the GtkPlot stuff, none of the other things in the library. No bugs or memory leaks that I am aware of. There used to be, but around 99.15 to 99.16 a lot got fixed. We were using an X server from Exceed, which grew in memory usage when updating plots; no idea whether Gtk, GtkPlot, or the X-server itself was at fault, but no such memory blleding was seen with the Sun X, Linux XFree86, or the Hummingbird product. It's a little quirky, I have problems positioning axis labels, etc., such that they look nice; my app is far from commercial-level beautiful. But I did clone the gtkrealtime demo and get my application plotting in short order. My biggest beef is that the documentation is near-zero, and the code is largely uncommented. When I did have to go in and figure out something about how tick/grid spacing was handled, it was a chore to read, although once I did understand it the code seemed to make sense and be very reasonable. The primary developer, Adrian Fenguin (spelling?) has been very responsive to questions on the list (I think he's in the process of moving, though, right now). Based on the changelog, I think that there is more development than the mailing list would indicate. Maybe discussion happens on the Scigraphica list.
