Core-plot and NSDate (iPhone)

Question

I want to build a line graph where the x axis is defined as the number of days between two dates, and the y axis is a value that changes on each day.

I can plot the y values ​​as NSNumber, but I don't know how to set the ranges and markup on the x axis. I looked at the date example in the "examples" directory of the main story distribution, but found it a bit confusing.

Does anyone know a tutorial or sample code that might interest me in this regard?

Thanks in advance.
