Viewing autopilot debug output (solved)

[flameout]

I know the PID implementation for FlightGear's autopilot has debug output. I also remember from somewhere there is a viewer for Linux that can view that output in real time (I found it, it's kst.) Is there any such viewer for Windows? I want to be able to view it in real-time graphs so I can learn to tune autopilots (probably using Ziegler-Nichols tuning.)
Thank you very much.
Edit: I found one (LiveGraph,) but I don't know if I can make it work.
Edit2: I didn't think I could find one, but after continued searching and work I got LiveGraph to work.
