An interface through which data in the form of (x, y) items can be accessed.
Method from org.jfree.data.xy.XYDataset Summary:
getDomainOrder,   getItemCount,   getX,   getXValue,   getY,   getYValue
Method from org.jfree.data.xy.XYDataset Detail:
 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. The x-values may or
may not be returned in ascending order, that is up to the class
implementing the interface.
 public double getXValue(int series,
    int item)
    Returns the x-value for an item within a series.
 public Number getY(int series,
    int item)
    Returns the y-value for an item within a series.
 public double getYValue(int series,
    int item)
    Returns the y-value (as a double primitive) for an item within a series.
