I have just open-sourced 'Narrative', the Cocoa plotting framework that
is used in my 'Trade Strategist' software. I have released it under the
LGPL, and it can be downloaded, or checked out via CVS, from
sourceforge:

Here is an introductory excerpt from the README file:
What is the Narrative Plotting Framework?
-----------------------------------------
Narrative is a framework written with Apple's Cocoa API for plotting on
Mac OS X. It is designed to be a complete plotting framework, rather
than a few lightweight classes. This makes the learning curve greater,
but leads to a powerful and extendible plotting solution. Nearly every
aspect of the framework can be modified or extended through subclassing
or delegation, in the best traditions of Cocoa design. The NSTableView
concept of a data source is used to supply plots with data, placing
very few restrictions on the form of data used, and how it is stored.
What license applies to Narrative?
----------------------------------
Narrative is open-source software, released under the GNU Lesser
General Public License (LGPL). Effectively this means you can use
Narrative in your own software, without open-sourcing the rest of your
code. If you make any changes to Narrative itself, you need to make the
source code of the changed version of Narrative available, but the rest
of your source code does not need to be made available. The idea behind
this licensing model is that everyone can use Narrative, and help
improve it, without any obligation to open-source other parts of their
software.
