public abstract class AbstractChartComposite
extends org.eclipse.swt.widgets.Composite
implements org.eclipse.core.runtime.jobs.IJobChangeListener

An abstract chart composite class. Inheriting from an SWT Composite, it can be used in UI classes. This class also implements the IJobChangeListener interface. It contains an AbstractDatasetCreator which creates the corresponding JFreeChart based charts, and by using this listener interface reacts to certain job events propagated by the dataset creator class.

Method Detail

initializeCreator

protected abstract AbstractDatasetCreator initializeCreator()

Initialized the dataset creator. Subclasses have to initialize their specialized creators.

Returns:

A JFreeChart dataset creator.

initializeChart

Initializes the chart.

Returns:

An initialized chart object.

refresh
