OpenGL ES-based graphics library for iPhone

Question

I am trying to draw large amounts of data, say, about a million data points in a line graph. I tried CorePlot, but it is somewhat lacking in speed. It could not even display 30,000 points at any useful rendering speed (less than 1 frame per second). s7graphview is somewhat similar to CorePlot, but with less features. I put together a simple OpenGL ES project and scored 1,000,000 points, and it displayed at about 10 frames per second, which is very useful for managing the graph. My question is, are there iPhone libraries based on OpenGL ES? If not, is there OpenGL open source that I can potentially port to iPhone? I would prefer not to resort to writing my own graphics library, if absolutely necessary.

Edit:

Good, since there is no one who would like to work with me to create the OpenGL ES graphics library open source?

Update:

I have finished my OpenGL graphics library. It can display 1,400,000 dots at 10 frames per second with multiple lines and multiple scales attached to these lines with dynamic resizing, and it is a standalone control that can be dropped to any window / view. Much better than CorePlot 10,000 points at 10 frames per second.
