Does anyone know of a native graphing library for the iPhone SDK? I have a free iPhone polling app called Show of Hands that currently uses calls to google charts via embedded safari pages, e.g. http://www.showofhands.mobi/Viewmore.aspx?qid=9245968c-d40d-478c-8781-804d086cd643 . Pros: free and easy and web-accessible. Cons: slower and less flexible within the app than native. So...I'm exploring options for handling the graphing and mapping functionality natively, without needing to roll my own.

Any suggestions?

Thanks!!

Thread on this here: Is there a good charting library for iPhone?

CorePlot seems to be the concensus so far, but still evolving.

This thread: Any good library for generating graphs for the iPhone? also had a great point:

In terms of embedding a JavaScript charting library, you can always use a WebKit view to host a web page containing whatever JavaScript you want. You will likely be interested in this sample code showing how to call into JS from Objective-C and visa versa.

You could try that with something like flot or other js libraries.
