Method Details

getDomainOrder

public DomainOrder getDomainOrder()
Returns the order of the domain (or X) values returned by the dataset.
Returns:
The order (never null).

getItemCount

public int getItemCount(int series)
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.
Parameters:
series - the series index (in the range 0 to getSeriesCount() - 1).
Returns:
The item count.

getX

public Number getX(int series,
                   int item)
Returns the x-value for an item within a series. The x-values may or may not be returned in ascending order, that is up to the class implementing the interface.
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 x-value (never null).

getXValue

public double getXValue(int series,
                        int item)
Returns the x-value for an item within a series.
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 x-value.

getY

public Number getY(int series,
                   int item)
Returns the y-value for an item within a series.
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 (possibly null).

getYValue

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