Interface XYDataset

    • Method Detail

      • getDomainOrder

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

        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

        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

        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

        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

        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.
