All Implemented Interfaces:

ChartModel

public abstract class AbstractChartModel

extends ChartModelSupport

implements ChartModel

Possible super class of a custom chart model. It manages the list of chart model listeners and has basic implementations of some members of the ChartModel interface.

Subclasses must at least implement the following methods:

• getRowCount()
• getColumnCount()
• getValueAt(int, int)

You have to call public void fireChartModelEvent(Object source) whenever your model changes.
