| DefaultXYDataset | | public class DefaultXYDataset extends AbstractXYDataset implements XYDataset,PublicCloneable(Code) | | A default implementation of the
XYDataset interface that stores
data values in arrays of double primitives.
since:
1.0.2 |
| Constructor Summary | |
| public | DefaultXYDataset()
Creates a new DefaultXYDataset instance, initially
containing no data. |
| Method Summary | |
| public void | addSeries(Comparable seriesKey, double[][] data)
Adds a series or if a series with the same key already exists replaces
the data for that series, then sends a
DatasetChangeEvent to
all registered listeners.
Parameters:
seriesKey - the series key (null not permitted).
Parameters:
data - the data (must be an array with length 2, containing two arrays of equal length, the first containing the x-values and thesecond containing the y-values). | | public Object | clone()
Creates an independent copy of this dataset. | | public boolean | equals(Object obj)
Tests this DefaultXYDataset instance for equality with an
arbitrary object. | | public DomainOrder | getDomainOrder()
Returns the order of the domain (x-) values in the dataset. | | public int | getItemCount(int series)
Returns the number of items in the specified series.
Parameters:
series - the series index (in the range 0 to getSeriesCount() - 1). | | public int | getSeriesCount()
Returns the number of series in the dataset. | | public Comparable | getSeriesKey(int series)
Returns the key for a series. | | public Number | getX(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 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 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 int | hashCode()
Returns a hash code for this instance. | | public int | indexOf(Comparable seriesKey)
Returns the index of the series with the specified key, or -1 if there
is no such series in the dataset.
Parameters:
seriesKey - the series key (null permitted). | | public void | removeSeries(Comparable seriesKey)
Removes a series from the dataset, then sends a
DatasetChangeEvent to all registered listeners. |
| DefaultXYDataset | | public DefaultXYDataset()(Code) | | Creates a new DefaultXYDataset instance, initially
containing no data.
|
| addSeries | | public void addSeries(Comparable seriesKey, double[][] data)(Code) | | Adds a series or if a series with the same key already exists replaces
the data for that series, then sends a
DatasetChangeEvent to
all registered listeners.
Parameters:
seriesKey - the series key (null not permitted).
Parameters:
data - the data (must be an array with length 2, containing two arrays of equal length, the first containing the x-values and thesecond containing the y-values). |
| equals | | public boolean equals(Object obj)(Code) | | Tests this DefaultXYDataset instance for equality with an
arbitrary object. This method returns true if and only if:
obj is not null;obj is an instance of
DefaultXYDataset;- both datasets have the same number of series, each containing
exactly the same values.
Parameters:
obj - the object (null permitted). A boolean. |
| getDomainOrder | | public DomainOrder getDomainOrder()(Code) | | Returns the order of the domain (x-) values in the dataset. In this
implementation, we cannot guarantee that the x-values are ordered, so
this method returns DomainOrder.NONE.
DomainOrder.NONE. |
| getItemCount | | public int getItemCount(int series)(Code) | | Returns the number of items in the specified series.
Parameters:
series - the series index (in the range 0 to getSeriesCount() - 1). The item count.
throws:
IllegalArgumentException - if series is not in the specified range. |
| getSeriesCount | | public int getSeriesCount()(Code) | | Returns the number of series in the dataset.
The series count. |
| getSeriesKey | | public Comparable getSeriesKey(int series)(Code) | | Returns the key for a series.
Parameters:
series - the series index (in the range 0 to getSeriesCount() - 1). The key for the series.
throws:
IllegalArgumentException - if series is not in the specified range. |
| 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.
throws:
ArrayIndexOutOfBoundsException - if series is not within the specified range.
throws:
ArrayIndexOutOfBoundsException - if item is not within the specified range.

| getYValue | | public double getYValue(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.
throws:
ArrayIndexOutOfBoundsException - if series is not within the specified range.
throws:
ArrayIndexOutOfBoundsException - if item is not within the specified range.

A hash code. |
| indexOf | | public int indexOf(Comparable seriesKey)(Code) | | Returns the index of the series with the specified key, or -1 if there
is no such series in the dataset.
Parameters:
