How to make drawing 2D graphs on obj-c?

Question

Objective-C

Hello. There is a task to make a library that can be connected to the project for drawing simple two-dimensional graphs by points. I would be glad of any information on how to start doing this, otherwise I have no idea how to approach this issue.
Thank you.

Answer 1

Here the question is complex. If there is not a lot of data, and there is no need to implement scrolling and zooming, then simply:
1. Inherit UIView
2. Create storage for data - coordinates
3. In drawRect: draw the necessary lines, background, points and anything you want using Core Graphics
