    • Method Detail

      • addSeries

        public void addSeries(VectorSeries series)
        Adds a series to the collection and sends a DatasetChangeEvent to all registered listeners.
        Parameters:
        series - the series (null not permitted).
      • removeSeries

        public boolean removeSeries(VectorSeries series)
        Removes the specified series from the collection and sends a DatasetChangeEvent to all registered listeners.
        Parameters:
        series - the series (null not permitted).
        Returns:
        A boolean indicating whether the series has actually been removed.
      • removeAllSeries

        public void removeAllSeries()
        Removes all the series from the collection and sends a DatasetChangeEvent to all registered listeners.
      • getSeries

        public VectorSeries getSeries(int series)
        Returns a series from the collection.
        Parameters:
        series - the series index (zero-based).
        Returns:
        The series.
        Throws:
        IllegalArgumentException - if series is not in the range 0 to getSeriesCount() - 1.
      • indexOf

        public int indexOf(VectorSeries series)
        Returns the index of the specified series, or -1 if that series is not present in the dataset.
        Parameters:
        series - the series (null not permitted).
        Returns:
        The series index.
      • getItemCount

        public int getItemCount(int series)
        Returns the number of items in the specified series.
        Specified by:
        getItemCount in interface XYDataset
        Parameters:
        series - the series (zero-based index).
        Returns:
        The item count.
        Throws:
        IllegalArgumentException - if series is not in the range 0 to getSeriesCount() - 1.
      • getXValue

        public double getXValue(int series,               int item)
        Returns the x-value for an item within a series.
        Specified by:
        getXValue in interface XYDataset
        Overrides:
        getXValue in class AbstractXYDataset
        Parameters:
        series - the series index.
        item - the item index.
        Returns:
        The x-value.
      • getX

        public Number getX(int series,          int item)
        Returns the x-value for an item within a series. Note that this method creates a new Double instance every time it is called---use getXValue(int, int) instead, if possible.
        Specified by:
        getX in interface XYDataset
        Parameters:
        series - the series index.
        item - the item index.
        Returns:
        The x-value.
      • getYValue

        public double getYValue(int series,               int item)
        Returns the y-value for an item within a series.
        Specified by:
        getYValue in interface XYDataset
        Overrides:
        getYValue in class AbstractXYDataset
        Parameters:
        series - the series index.
        item - the item index.
        Returns:
        The y-value.
      • getY

        public Number getY(int series,          int item)
        Returns the y-value for an item within a series. Note that this method creates a new Double instance every time it is called---use getYValue(int, int) instead, if possible.
        Specified by:
        getY in interface XYDataset
        Parameters:
        series - the series index.
        item - the item index.
        Returns:
        The y-value.
      • getVector

        public Vector getVector(int series,               int item)
