The DrillDown JavaBean-Features

  • The design is based on MVC architechture pioneered by SmallTalk
  • Creating chart is a simple 4 step process
    1. Create an instance of Bean
    2. Add the bean to a container
    3. Tell the Bean about the Views you want
    4. Instantiate the Bean with data
    (If you use JavaScript the Bean has been created and added to the wrapper applet. Only 2 steps, 3 and 4 are required.)
  • Rich set of properties and methods enable you to customise to your specific needs.
  • Some visual properties can be modified by end user at runtime !
