Class XYDatasetTableModel

  • All Implemented Interfaces:
    java.io.Serializable, java.util.EventListener, javax.swing.table.TableModel, DatasetChangeListener
    public class XYDatasetTableModel
extends javax.swing.table.AbstractTableModel
implements javax.swing.table.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)
