When developing for iOS, a few times I was working on a bespoke graph, either copying a design created by someone else or implementing strict design guidelines. I decided to share the experience I've gained then in a series of articles. Here they are:
Part 1. Preparing the environment, drawing the grid lines.
Part 2. Drawing a bar graph, with gradient fill.
Part 3. Drawing a line graph, with gradient fill.
Part 4. Making graphs interactive.
Part 5. (to be published soon) Drawing text on graphs (labels etc).
Hello,
ReplyDeletethank you for the very nice and helpful tutorial.
Please, can you explain how I could display the index and value from a "touched" bargraph (Part 4) to labels, placed on the MainView (ViewController)?
Thanks again and best wishes
Uwe
