OpenGL Luminous And Graph Building

Hey guys

First off I was wondering if anybody has experience using Luminous an opengl library and also

I am trying to create a graph basically with a set of value from which I have parsed from xml files(value, date) and basically I need to display them value against the date. I was wondering if anybody has ever done something like this and if they could out me in the right direction on how to go about achieving this?

Thanks alot
