If you want to add graphs to your Cocoa applications on Mac OS X (Panther) then check out:

http://www.vvi.com/download/vvidgetcode

Where there is a Xcode project and Cocoa application source code example showing how to place graphs, from line graphs to 3D surface graphs, into your own applications. It is freeware. The download packages explains it all.

Now, instead of using a graphing, spreadsheet or scripting application, you can build your own. And, best of all, you are not constrained by a limited set of algorithms. You can insert your own model or data source into the Xcode project, rebuild, and off you go automatically generating results. Whether your data source is a complex nonlinear model, hardware acquisition, database server or a simple arithmetic expression you are set to go. Because it uses Apple's Xcode it can be Applescript driven or programmed in Objective-C, ANSI-C and C++.

A perfect solution for analysts and scientists because they don't have to manually import data to a graphing application and because it is easy to program and understand. That means less time trying to get data to a form where it can be understood, and more time understanding results.
