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.

You can create a chart for your data in Excel for the web. Depending on the data you have, you can create a column, line, pie, bar, area, scatter, or radar chart. Click anywhere in the data for which you want to create a chart. To plot specific data into a chart, you can also select the data.
The Objective-C runtime is a runtime library that provides support for the dynamic properties of the Objective-C language, and as such is linked to by all Objective-C apps. Objective-C runtime library support functions are implemented in the shared library found at /usr/lib/libobjc.
Swift has better memory management features than Objective-C, which can help improve performance. It uses lazy initialization, reducing memory usage since unused variables do not initialize—making it faster, easier to read and write, and safer.
Objective-C is the primary programming language you use when writing software for OS X and iOS. It's a superset of the C programming language and provides object-oriented capabilities and a dynamic runtime.
I use Core Plot. See this blog post for a tutorial.

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

you can have a look at DSBarChart. It is a tiny library for creating Histograms.
