Class XYDatasetTableModel

public class XYDatasetTableModel extends AbstractTableModel implements TableModel, DatasetChangeListener

A READ-ONLY wrapper around a TableXYDataset to convert it to a table model for use in a JTable. The first column of the table shows the x-values, the remaining columns show the y-values for each series (series 0 appears in column 1, series 1 appears in column 2, etc).

TO DO:

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

Constructor Summary
	XYDatasetTableModel() Default constructor.
	XYDatasetTableModel(TableXYDataset dataset) Creates a new table model based on the specified dataset.

Method Summary
void	datasetChanged(DatasetChangeEvent event) Receives notification that the underlying dataset has changed.
int	getColumnCount() Gets the number of columns in the model.
String	getColumnName(int column) Returns the column name.
int	getRowCount() Returns the number of rows.
Object	getValueAt(int row, int column) Returns a value of the specified cell.
boolean	isCellEditable(int row, int column) Returns a flag indicating whether or not the specified cell is editable.
void	setModel(TableXYDataset dataset) Sets the model (dataset).
void	setValueAt(Object value, int row, int column) Updates the XYDataset if allowed.
