Graph generation on iPhone
Anyone have experience with drawing graphs on the iPhone? Looks like GraphKit isn't an option, so it's up to the programmer to either write his own library (using OpenGL, I guess), or an existing library. I can't seem to find any libraries that are confirmed to work on the iPhone.
If you've written your own how did you go about it (opengl, quartz, etc), or if you used a library which one?
