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.

Answer 2

Core Plot is an outstanding project. The past year I have faced the prospect that I was going to have to do all of this by hand. (I'm writing an application that compares metagenomic DNA sequences and graphs the results). Core Plot while still a small project currently fills a niche that I think is only going to grow, especially in the scientific community. List of blog posts on using it from their own wiki here

Answer 3

I'll echo the suggestion of core-plot, and add some additional plotting references that may be of interest:
