Interface VectorXYDataset

    • Method Detail

      • getVectorXValue

        double getVectorXValue​(int series,
                               int item)
        Returns the x-component of the vector for an item in a series.
        Parameters:
        series - the series index.
        item - the item index.
        Returns:
        The x-component of the vector.
      • getVectorYValue

        double getVectorYValue​(int series,
                               int item)
        Returns the y-component of the vector for an item in a series.
        Parameters:
        series - the series index.
        item - the item index.
        Returns:
        The y-component of the vector.
      • getVector

        Vector getVector​(int series,
                         int item)
        Returns the vector for an item in a series. Depending on the particular dataset implementation, this may involve creating a new Vector instance --- if you are just interested in the x and y components, use the getVectorXValue(int, int) and getVectorYValue(int, int) methods instead.
        Parameters:
        series - the series index.
        item - the item index.
        Returns:
        The vector (possibly null).
