Take a look at Core Plot. It's a library that runs on iOS and Mac OS, and supports a variety of different types of graphs and plots.

If all you need is a single line, with no keys or labels, you might look at UIBezierPath. That class lets you create and draw a path object. At it's simplest, the path could be a connected series of points. You'd create a custom subclass of UIView, and override the drawRect method. In drawRect, you'd draw a UIBezierPath to draw your line graph.

So go download CorePlot from the Google code site at Downloads - core-plot - Cocoa plotting framework for Mac OS X and iOS - Google Project Hosting and try it out.

Edit: I just downloaded it from that link, and there are ELEVEN sample applications included.

That should be enough to get you started, methinks.
