FreeGraph is more recent than GraphIt and it has some additional features and options. Both can graph functions, graph parametric equations, zoom and trace the graph, solve equations, and evaluate expressions. FreeGraph can add/subtract/multipy/divide fractions and can convert fractions to decimal and back (with repeating decimals displayed properly.) FreeGraph also will graph a set of points and determine the best fit line.

Info on Binaries: Unfortunately, I can not find the source code for these Windows applications which were written in Delphi at least 5 years ago. I recently had a request to buy a copy, and by some miracle I found these binaries. I did find a diskette labeled "Graphit Source Code," but when I tried to read it, it had been changed to a Linux boot disk.

This windows version of Freegraph has some interesting features with fractions and more options for display. GraphIt is kind of nice, but has an ugly gray background (which can't be changed) for the graph and the help file is not very useful. The good new is, it runs on Windows 3.1...believe it or not. (They both have some slight issues with window sizes on XP, but still work. They seemed good on W2K.)

After looking at it, I thought it'd be nice to have some of the features in the Java freegraph, especially the fractions stuff and the expression evaluator. If someone would like to write then in Java, I'd love to add them to the Java Freegraph page.
