SM2DGraphView framework provides an NSView subclass which draws pie charts or graphs of lines and/or bars including axis labels.
The SM2DGraphView class acts very much like an NSTableView or NSBrowser; SM2DGraphView takes responsibility for all of the drawing code but relies on a data source object to provide the specific lines and points to draw. A delegate object can also be assigned to a graph object to modify the behavior of the graph view.
Includes Interface Builder (IB) palette to easily add graphs to your nib files.
Version 1.5.1: Fixed the dataSource link in the IB3 Plugin .classDescription files. Now the IB3 plugin will remember the connection set for the datasource of either a pie chart or graph.
EVERYDAY SOFTWARE Absolutely excellent. Great Apple-like API, customizable, fast, easy to use and a liberal license. I can't think of anything else I'd want to see in this project. (Version 1.5.1)
