Hi!

Does anyone know of a good OpenGL plotting/graphing library I can use  
from  
Ruby’s OpenGL module? I’m writing a monitoring application in Ruby, and  
I  
just want to generate real time 2D plots.

Thanks!

Probably a dumb question: if you want 2D, why not use rrdtool (and its  
ruby bindings) instead of opengl? Is it not realtime enough?

Because I’m stupid and didn’t know of it’s existence. Any more tools  
alone  
these lines you’d like to share with me?

Thanks!

tioga ([http://www.kitp.ucsb.edu/~paxton/tioga.html](http://www.kitp.ucsb.edu/~paxton/tioga.html)) looks nice.

Still, I don’t think either rrdtool or tioga are real-time in the sense  
of watching the plot drawn as time advances, like in the KDE system  
guard or the windows equivalent. (Hope I’m wrong…)
