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

item - the item index (in the range 0 to getItemCount(series)).

Returns:

The x-value.

public double getStartXValue(int series,
 int item)

Description copied from interface: IntervalXYDataset

Returns the lower bound of the x-interval (as a double primitive) for the specified series and item.

Specified by:

getStartXValue in interface IntervalXYDataset

Parameters:

series - the series (zero-based index).

item - the item (zero-based index).

Returns:

The lower bound of the x-interval.

See Also:

• IntervalXYDataset.getStartX(int, int)

getEndXValue

public double getEndXValue(int series,
 int item)

Description copied from interface: IntervalXYDataset

Returns the upper bound of the x-interval (as a double primitive) for the specified series and item.

Specified by:

getEndXValue in interface IntervalXYDataset

Parameters:

series - the series index (zero-based).

item - the item index (zero-based).

Returns:

The upper bound of the x-interval.

See Also:

• IntervalXYDataset.getEndX(int, int)

getYValue

public double getYValue(int series,
 int item)

Description copied from interface: XYDataset

Returns the y-value (as a double primitive) for an item within a series.

Specified by:

getYValue in interface XYDataset

Parameters:

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

item - the item index (in the range 0 to getItemCount(series)).

Returns:

The y-value.

getItemCount

public int getItemCount(int series)

Description copied from interface: XYDataset

Returns the number of items in a series.

It is recommended that classes that implement this method should throw an IllegalArgumentException if the series argument is outside the specified range.

Specified by:

getItemCount in interface XYDataset

Parameters:

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

Returns:

The item count.

getEndX

public Number getEndX(int series,
 int item)

Description copied from interface: IntervalXYDataset

Returns the upper bound of the x-interval for the specified series and item. If this upper bound is specified, it should be greater than or equal to the lower bound of the interval (if one is specified).

Specified by:

getEndX in interface IntervalXYDataset

Parameters:

series - the series index (zero-based).

item - the item index (zero-based).

Returns:

The upper bound of the x-interval (null permitted).

getEndY

public Number getEndY(int series,
 int item)

Description copied from interface: IntervalXYDataset

Returns the upper bound of the y-interval for the specified series and item. If this upper bound is specified, it should be greater than or equal to the lower bound of the interval (if one is specified).

Specified by:

getEndY in interface IntervalXYDataset

Parameters:

series - the series index (zero-based).

item - the item index (zero-based).

Returns:

The upper bound of the y-interval (null permitted).

getEndYValue

public double getEndYValue(int series,
 int item)

Description copied from interface: IntervalXYDataset

Returns the upper bound of the y-interval (as a double primitive) for the specified series and item.

Specified by:

getEndYValue in interface IntervalXYDataset

Parameters:

series - the series index (zero-based).

item - the item index (zero-based).

Returns:

The upper bound of the y-interval.

See Also:

• IntervalXYDataset.getEndY(int, int)

getStartX

public Number getStartX(int series,
 int item)

Description copied from interface: IntervalXYDataset

Returns the lower bound of the x-interval for the specified series and item. If this lower bound is specified, it should be less than or equal to the upper bound of the interval (if one is specified).

Specified by:

getStartX in interface IntervalXYDataset

Parameters:

item - the item index (zero-based).

Returns:

The lower bound of the x-interval (null permitted).

getStartY

public Number getStartY(int series,
 int item)

Description copied from interface: IntervalXYDataset

Returns the lower bound of the y-interval for the specified series and item. If this lower bound is specified, it should be less than or equal to the upper bound of the interval (if one is specified).

Specified by:

getStartY in interface IntervalXYDataset

Parameters:

Returns:

The lower bound of the y-interval (null permitted).

getStartYValue

public double getStartYValue(int series,
 int item)

Description copied from interface: IntervalXYDataset

Returns the lower bound of the y-interval (as a double primitive) for the specified series and item.

Specified by:

getStartYValue in interface IntervalXYDataset

Parameters:

getX

public Number getX(int series,

Specified by:

getX in interface XYDataset

Parameters:

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

item - the item index (in the range 0 to getItemCount(series)).
