}

Default constructor.

 public XYDatasetTableModel(TableXYDataset dataset) 
{
        this();
        this.model = dataset;
        this.model.addChangeListener(this);
}

Creates a new table model based on the specified dataset.

Parameters:

dataset - the dataset.

 public  void datasetChanged(DatasetChangeEvent event) 
{
        fireTableDataChanged();
}

Receives notification that the underlying dataset has changed.

 public int getColumnCount() 
{
        if (this.model == null) {
            return 0;
        }
        return this.model.getSeriesCount() + 1;
}

Gets the number of columns in the model.

 public String getColumnName(int column) 
{
        if (this.model == null) {
            return super.getColumnName(column);
        }
        if (column <  1) {
            return "X Value";
        }
        else {
            return this.model.getSeriesKey(column - 1).toString();
        }
}

Returns the column name.

 public int getRowCount() 
{
        if (this.model == null) {
            return 0;
        }
        return this.model.getItemCount();
}

Returns the number of rows.

 public Object getValueAt(int row,
    int column) 
{
        if (this.model == null) {
            return null;
        }
        if (column <  1) {
            return this.model.getX(0, row);
        }
        else {
            return this.model.getY(column - 1, row);
        }
}

Returns a value of the specified cell. Column 0 is the X axis, Columns 1 and over are the Y axis

 public boolean isCellEditable(int row,
    int column) 
{
        return false;
}

Returns a flag indicating whether or not the specified cell is editable.

 public  void setModel(TableXYDataset dataset) 
{
        this.model = dataset;
        this.model.addChangeListener(this);
        fireTableDataChanged();
}

Sets the model (dataset).

 public  void setValueAt(Object value,
    int row,
    int column) 
{
        if (isCellEditable(row, column)) {
            // XYDataset only provides methods for reading a dataset...
        }
}

Updates the XYDataset if allowed.
