Graphs math equations.

Overview

Graph550 is a program to graph mathematical equations. Simply input a specially formatted equation, and it will graph it for you. It currently supports functions specified in terms of x, functions specified in terms of y, and parameterized equations. It also allows for precisely determining the view, and control of how the function is graphed. Once you create a graph, you can print it out, or export it to PDF, PostScript, or TIFF format.

Graph550 is what I like to call "Feature Request Ware". The idea is to give people a fully functioning product, with no annoying popups. But as I'm busy with class and work, I don't have time to add all the features people would want. So basically, if you really want a feature, you can "donate" money to help fund development. Whichever suggestion is the one I'm most likely to develop. To make a feature request, just email me. I haven't decided on a payment method; Pay Pal won't work because I've heard there are a lot of issues related to it. If I ever decide to go to a different license, anyone who donates will be guaranteed lifetime license.

I'm not sure what all's new in the latest update; dev doesn't have any version history. I think the "dotted line" feature is new, and I don't remember being able to export directly to PDF and PostScript before. So I guess that's what's new.

This is probably the best interface I could possibly imagine for a program like this. It's right up there with the best interfaces I've seen for any kind of app on Mac OS X, and Mac OS X itself is the platform with the most excellent interface design by far. Plotting graphs is maybe not the most complicated thing to do on a computer, but this app makes it as simple as it can possibly be. And pretty! Graph550 is even better than Algebra Graph which was bundled with OS 8... and back then I thought this could not be done any better. Brilliant.

This is a very fine programme indeed and fulfils a real need. The ability to plot several different functions simultaneously and to include a 'variation' variable to each plot are very neat features

Excellent. I'm far to cheap to purchase a graphing calculator, and I resent having to launch Classic to open PacificT's Graphing Calculator. Furthermore, Graphing Calculator won't graph multiple equations in the free program. So Graph550 meets my needs perfectly. Great piece of freeware.

Very nice and simple. I like where this program is going. It just needs some polishing math-wise (pretty asymptotes, undefined discontinuities, correct definition of ln and log, etc) and it'll be perfect.

Nice app. Simple, OS-Xey, small, priced right. In 1 minute I found out that lim as x->infinity of ((x+1)/x)^x=e. Thanks.

Nice little app for visualizing functions. It's not however, the only freeware graphing app for OS-X. There are some more powerful choices like MathPad or Python.
