Package org.jfree.data

Class XYDatasetTableModel

java.lang.Object

javax.swing.table.AbstractTableModel

org.jfree.data.XYDatasetTableModel

All Implemented Interfaces:

Serializable, EventListener, TableModel, DatasetChangeListener

public class XYDatasetTableModel
extends AbstractTableModel
implements TableModel, DatasetChangeListener

A READ-ONLY wrapper around an XYDataset to convert it to a table model for use in a JTable.

TO DO:

• implement proper naming for x axis (getColumnName)
• implement setValueAt to remove READ-ONLY constraint (not sure how)
