Developing Chart Classes
Define your own chart class by creating a subclass of the
ChartContainer base class. If you write scripts or functions for creating
specialized visualizations and share them with others, consider creating a class
implementation. Creating a class enables you to provide a convenient interface for your users.
When they want to customize aspects of your chart, they can set properties rather than having
to modify and rerun your graphics code. You design your own custom set of properties and
control which ones your users can access. Users can modify properties at the command line or
inspect them in the Property Inspector. Instances of your class are members of the graphics
object hierarchy. As a result, your charts are compatible with many aspects of the graphics
system. For more information, see Chart Development Overview.
