Part IV, Chapter 16 through Chapter 21, focuses on building our last major application, called GraphPaper. Given a range and step, GraphPaper will graph a mathematical function in color and use mouseovers to identify graph points. We also embed in GraphPaper many of the standard features of commercial Mac OS X applications, such as services, copy and paste, and the use of the Mac OS X preferences database.
