The devices we carry in our pockets everyday are becoming increasingly complex and are able to capture and log more data than ever before. As a result, it is inevitable that in an upcoming meeting you will be asked to do the following:

“We want charts. Bar charts, line graphs, pie charts, lots of stats, a graph for every person, every place, every hashtag, every action – we want to show it all”…..”Oh, and wouldn’t it be cool if it animated into place too?”

Dust off your middle-school geometry folks, because today with Core Graphics  we’re going to draw some graphs.

This talk covers the following:

  • UIView Properties
  • CALayer View Properties
  • UI Bezier Paths (Lines & Shapes)
