| XYDataset | | public interface XYDataset extends SeriesDataset(Code) | | An interface through which data in the form of (x, y) items can be accessed.
|
| Method Summary | |
| public DomainOrder | getDomainOrder()
Returns the order of the domain (or X) values returned by the dataset. | | 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. | | public Number | getX(int series, int item)
Returns the x-value for an item within a series. | | 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).
Parameters:
item - the item index (in the range 0 to getItemCount(series)). | | 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).
Parameters:
item - the item index (in the range 0 to getItemCount(series)). | | 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).
Parameters:
item - the item index (in the range 0 to getItemCount(series)). |
| getDomainOrder | | public DomainOrder getDomainOrder()(Code) | | Returns the order of the domain (or X) values returned by the dataset.
The order (never null). |
| getItemCount | | public int getItemCount(int series)(Code) | | 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). The item count. |
| getX | | public Number getX(int series, int item)(Code) | | 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).
Parameters:
item - the item index (in the range 0 to getItemCount(series)). The x-value (never null). |
| getXValue | | public double getXValue(int series, int item)(Code) | | Returns the x-value for an item within a series.
Parameters:
series - the series index (in the range 0 to getSeriesCount() - 1).
Parameters:
item - the item index (in the range 0 to getItemCount(series)). The x-value. |
| getY | | public Number getY(int series, int item)(Code) | | Returns the y-value for an item within a series.
Parameters:
series - the series index (in the range 0 to getSeriesCount() - 1).
Parameters:
item - the item index (in the range 0 to getItemCount(series)). The y-value (possibly null). |
| getYValue | | public double getYValue(int series, int item)(Code) | | 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).
Parameters:
item - the item index (in the range 0 to getItemCount(series)). The y-value. |
