Developing Chart Classes - MATLAB & Simulink (original) (raw)
Main Content
Author your own class of custom chart objects
Define your own chart class by creating a subclass of theChartContainer 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.
