For example, the Application Kit doesn’t contain any classes for plotting graphs. Therefore, it is necessary to subclass NSView, an Application Kit class, to create such graphics.

There are several ways to draw when implementing a subclass of NSView. The first and most common way is to use Quartz 2D graphics. Another is to use Cocoa’s support ...
