cocoa - Objective-C Charting Framework

Question

I'm in urgent need of an Objective-C/Cocoa/Cocoa Touch framework to handle simple charting; pie chards, histograms etc.

The only thing that comes close is:

http://code.google.com/p/gchart-objc/

But it seems to be quite an early release and not maintained.

Has anyone created or used such a framework or library.

Answer 1

I use Core Plot. See this blog post for a tutorial.
