How can I create a line graph in CorePlot?

[Varun Lakshmanan]

I'm using the [CorePlot](https://github.com/core-plot/core-plot) framework and I'm having some trouble setting up a basic scatterplot. Essentially, I have an array of values that the user can add to over time. The scatterplot should graph all of the values in the array and connect them with a line (the color, thickness, etc of the line doesn't matter). If it matters, the graph will be in a secondary view controller and the data for the line graph will be imported from the main view controller. I've already looked through the examples provided and I've read [the tutorial on this website](https://web.archive.org/web/20120805115026/http://www.raywenderlich.com/13271/how-to-draw-graphs-with-core-plot-part-2), but neither help me in what I'm doing. 

Can I have step-by-step instructions with sample code (in Objective-C) on how to implement this line graph/scatterplot in my application?

Which part are you having trouble with? Setting up the graph? Updating the data over time?

I'm having trouble actually creating the graph, setting up the axes and lines, and integrating the data I need to graph.

I found [this tutorial](http://www.mobdevel.com/?p=96) online. Will it be sufficient for what I'm doing or is the code outdated?
