OpenGL ES based graphing library for iPhone

I'm trying to graph large amounts of data, say around a million data points in a line graph. I've tried CorePlot, but it is somewhat lacking in speed. It couldn't even graph 30,000 points with any sort of usable rendering speed (less than 1 fps). s7graphview is somewhat similar to CorePlot but with less features. I put together a simple OpenGL ES project and graphed 1,000,000 points and it rendered at around 10 fps, which is a very usable speed for manipulating a graph. My question is thi开发者_如何学编程s, are there any purely OpenGL ES based graphing libraries for the iPhone? If not, are there any open source OpenGL based ones I could potentially port to the iPhone? I'd rather not resort to writing my own graphing library unless absolutely necessary.

Edit:

Ok, since there aren't any takers, would anyone be willing to work together with me to make an Open Source OpenGL ES graphing library?

Update:

I've finished my OpenGL graphing library. It can graph 1,400,000 points at 10 fps with multiple lines and multiple scales attached to those lines, with dynamic resizing and it is a self contained control that can be dropped onto any window/view. Much better than CorePlot's 10,000 points at 10 fps.
