public class DBXYCategoryDataset
extends DBXYDataset

An implementation of DBXYDataset that dynamically creates distinct series for different categories. The categories are defined by the values of a DB table column.

Method Details

setLocalTable

public void setLocalTable(ReplicatedTable table)

Description copied from class: DBXYDataset

Sets the DBXYDataset.localTable that this dataset will use as its data source. Calling code should subsequently invoke DBXYDataset.fireTableDataChanged() on the event dispatch thread.

Specified by:

setLocalTable in interface DBDataset

Overrides:

setLocalTable in class DBXYDataset

See Also:

• DBDataset.setLocalTable(ReplicatedTable)

getSeriesCount

public int getSeriesCount()

Returns the number of series in this dataset. This is the number of series defined for the chart times the number of categories

Specified by:

getSeriesCount in interface org.jfree.data.general.SeriesDataset

Overrides:

getSeriesCount in class DBXYDataset

Returns:

getSeriesKey

public Comparable getSeriesKey(int series)

Specified by:

getSeriesKey in interface org.jfree.data.general.SeriesDataset

Overrides:

getSeriesKey in class DBXYDataset

getCategoriesCount

public int getCategoriesCount()

getItemCount

public int getItemCount(int series)

Specified by:

getItemCount in interface org.jfree.data.xy.XYDataset

Overrides:

getItemCount in class DBXYDataset

getX

public Number getX(int series,
 int item)

Specified by:

getX in interface org.jfree.data.xy.XYDataset

Overrides:

getX in class DBXYDataset

getY

public Number getY(int series,
 int item)

Specified by:

getY in interface org.jfree.data.xy.XYDataset

Overrides:

getY in class DBXYDataset

fireTableDataChanged

public void fireTableDataChanged()

Description copied from interface: DBDataset

Notifies this DBDataset that the data in the table used as its data source has changed, or that the entire source table itself has changed (such as with DBDataset.setLocalTable(ReplicatedTable).

If an implementation of fireTableDataChanged() calls AbstractDataset.fireDatasetChanged(), or otherwise interacts with JFreeChart, then this method should only be called on the event dispatch thread. (See SwingUtilities.invokeLater().)

Specified by:

fireTableDataChanged in interface DBDataset

Overrides:

fireTableDataChanged in class DBXYDataset
