Method Detail

getSeriesCount

public abstract int getSeriesCount()

Returns the number of series in the dataset.

Specified by:

getSeriesCount in interface SeriesDataset

Returns:

The series count.

getSeriesKey

public abstract java.lang.Comparable getSeriesKey(int series)

Returns the key for a series.

If series is not within the specified range, the implementing method should throw an IndexOutOfBoundsException (preferred) or an IllegalArgumentException.

Specified by:

getSeriesKey in interface SeriesDataset

Parameters:

series - the series index (in the range 0 to getSeriesCount() - 1).

Returns:

The series key.

indexOf

public int indexOf(java.lang.Comparable seriesKey)

Returns the index of the named series, or -1.

Specified by:

indexOf in interface SeriesDataset

Parameters:

seriesKey - the series key (null permitted).

Returns:

The index.

seriesChanged

public void seriesChanged(SeriesChangeEvent event)

Called when a series belonging to the dataset changes.

Specified by:

seriesChanged in interface SeriesChangeListener

Parameters:

event - information about the change.
