I have just finished my first appraoch to push fgplot into some classes.
Should be used as standalone or plugged in into another ( controling ) program.
You cannot have just a line, that's the point here.
If you dare to try, don't forget you need the last updates of flightgear and simgear and also osg. That is because
of the use of the mouse-buttons to work a little more easy.
There is a problem in resizing which can and will, crash your flightgear ! But only if you resize rapidly and continues.
Must be a bug, but I do not see it. But funny to see how the color become white and all freezes. Then it crashes.
If the masters of canvas and nasal would give it a try..... Read the PReadme first to get the first idea of the program and the classes. it is not 100% as requested, but thats how it it works with me....
If you want to have a talk on skype... send an email or privmessage.

Edit: O, I forgot, you can start as much as your system allows. I ran 10 of these together...
And, it is full of debug messages.. it is not cleaned at all !
