Constructor Detail

VectorSeriesCollection

public VectorSeriesCollection()

Creates a new instance of VectorSeriesCollection.

Method Detail

addSeries

public void addSeries(VectorSeries series)

Adds a series to the collection and sends a DatasetChangeEvent to all registered listeners.

Parameters:

series - the series (null not permitted).

removeSeries

public boolean removeSeries(VectorSeries series)

Removes the specified series from the collection and sends a DatasetChangeEvent to all registered listeners.

Parameters:

series - the series (null not permitted).

Returns:

A boolean indicating whether the series has actually been removed.

removeAllSeries

public void removeAllSeries()

Removes all the series from the collection and sends a DatasetChangeEvent to all registered listeners.

getSeriesCount

public int getSeriesCount()

Returns the number of series in the collection.

Specified by:

getSeriesCount in interface SeriesDataset

Specified by:

getSeriesCount in class AbstractSeriesDataset

Returns:

The series count.

getSeries

public VectorSeries getSeries(int series)

Returns a series from the collection.

Parameters:

series - the series index (zero-based).

Returns:

The series.

Throws:

java.lang.IllegalArgumentException - if series is not in the range 0 to getSeriesCount() - 1.

getSeriesKey

public java.lang.Comparable getSeriesKey(int series)

Returns the key for a series.

Specified by:

getSeriesKey in interface SeriesDataset

Specified by:

getSeriesKey in class AbstractSeriesDataset

Parameters:

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

Returns:

The key for a series.

Throws:

java.lang.IllegalArgumentException - if series is not in the specified range.

indexOf

public int indexOf(VectorSeries series)

Returns the index of the specified series, or -1 if that series is not present in the dataset.

Parameters:

series - the series (null not permitted).

Returns:

The series index.

getItemCount

public int getItemCount(int series)

Returns the number of items in the specified series.

Specified by:

getItemCount in interface XYDataset

Parameters:

series - the series (zero-based index).

Returns:

The item count.

Throws:

java.lang.IllegalArgumentException - if series is not in the range 0 to getSeriesCount() - 1.

getXValue

public double getXValue(int series,
                        int item)

Returns the x-value for an item within a series.

Specified by:

getXValue in interface XYDataset

Overrides:

getXValue in class AbstractXYDataset

Parameters:

series - the series index.

item - the item index.

Returns:

The x-value.

getX

public java.lang.Number getX(int series,
                             int item)

Returns the x-value for an item within a series. Note that this method creates a new Double instance every time it is called---use getXValue(int, int) instead, if possible.

Specified by:

getX in interface XYDataset

Parameters:

series - the series index.

item - the item index.

Returns:

The x-value.

getYValue

public double getYValue(int series,

Specified by:

getYValue in interface XYDataset

Overrides:

getYValue in class AbstractXYDataset

Parameters:

series - the series index.

item - the item index.

Returns:

The y-value.

getY

public java.lang.Number getY(int series,
                             int item)

Returns the y-value for an item within a series. Note that this method creates a new Double instance every time it is called---use getYValue(int, int) instead, if possible.

Specified by:

getY in interface XYDataset

Parameters:

series - the series index.
