GraphPlot v1.3.2

To obtain help, use the ‘GraphPlot Help’ command which in the Help menu under System 7, or in the Apple Menu under System 6. Balloon help is also available under System 7.

Graphplot is an application for creating graphs for mathematical, scientific or engineering documentation, or just for exploring mathematical functions. It grew out of the need to incorporate fairly complex and nicely presented graphs into coursework carried out whilst the author was a student. At that time no cheap package (vital for students!) was available that could create graphs of this kind, and as far as I know, there still isn’t.

This program is made available as shareware, and is aimed at students, although it is hoped that the quality of the graphs produced may attract more ‘professional’ users. If you use this program, all I ask is £10 Sterling (or local equivalent, say, $20 US Dollars, 25 Deutschmarks, 100 French Francs, etc...) in return for all the hours I slaved over a steaming keyboard hacking all that glorious ‘C’ code together...

Credits

Credit is due to Steve Baxter for providing enough clues to get the algebraic formula analysis to work properly. (Check out Steve’s game ‘Winroids’ on the PC- it’s class! [a pity about the operating system though...])
Concurrency is provided by the Threads package from Apple Computer Advanced Technology Group (ATG), written by Michael Gough,  Joe MacDougald, Tom Dowdy, Jed Harris, et. al. Code is based on an article in Develop magazine, Issue 6.
Thanks also to Randy Theland and Brigham Stevens of Apple Computer DTS for the rotated text routine (used here in modified form). Many, many thanks to everyone who has sent in their shareware fees and constructive comments and criticism- GraphPlot will continue to evolve and improve as long as you folks keep this up!
Finally, love to Martina and Miriam for giving me such a wonderful time in España, April 1993...
