making graphs with xCode [closed]

Question

Hi I need to graph some arrays to analyse signals, I have a cocoa project going. Can anyone tell me where I can find tools to simplify this task?

Basically i want to display my arrays like on a graphing calculator.

Answer 1

Even though it's a young library, I'd suggest looking at the open source Core Plot framework. It works on Mac and iPhone and can currently plot line and bar charts. As I said, it's young and a lot of the core functionality is still being written, but it might work right now for your case.

Answer 2

Take a look at this post to the Apple mailing lists. http://lists.apple.com/archives/scitech/2007/Jun/msg00022.html

It mentions 3 potential graphing packages that you can try. I have not had personal experience with them, so buyer beware, but it will at least give you a start on where to look.
