Hi Gipe Cody,

Good day! I would recommend you to view YouTube's tutorials on their website YouTube.com and search there drawing graphs using openGL. There are list of tutorials that are available in playlist for full tutorial from lesson 1 to lesson N, depending on the author's way of sharing things.
