Extracting data from a graph

[karamel]

Hi!

I want to make a program that plots some data, so I can zoom in the obtained graph and then extract the data only from this portion of the graph. Extracting the data should be made by pressing a button and automatically creating an array. Is it possible?

Thanks,

Gina

Sure. All you really need to do is get the XScale's range so you know the start and stop of where to extract the data that was fed into the graph. See attached crude example (doesn't handle rounding and all that) that should get you started.
