  • All Superinterfaces:
    Dataset, SeriesDataset, XYDataset
    All Known Implementing Classes:
    DefaultBoxAndWhiskerXYDataset


    public interface BoxAndWhiskerXYDatasetextends XYDataset
    An interface that defines data in the form of (x, max, min, average, median) tuples.

    Example: JFreeChart uses this interface to obtain data for AIMS max-min-average-median plots.

        The Q1 median-value for the specified series and item.
      • getQ3Value

        Number getQ3Value(int series,                int item)
        Returns the Q3 median-value for the specified series and item.
        Parameters:
        series - the series (zero-based index).
        item - the item (zero-based index).
        Returns:
        The Q3 median-value for the specified series and item.
      • getMinRegularValue

        Number getMinRegularValue(int series,                        int item)
        Returns the min-value for the specified series and item.
        Parameters:
        series - the series (zero-based index).
        item - the item (zero-based index).
        Returns:
        The min-value for the specified series and item.
      • getMaxRegularValue

        Number getMaxRegularValue(int series,                        int item)
        Returns the max-value for the specified series and item.
        Parameters:
        series - the series (zero-based index).
        item - the item (zero-based index).
        Returns:
        The max-value for the specified series and item.
      • getMinOutlier

        Number getMinOutlier(int series,                   int item)
        Returns the minimum value which is not a farout.
        Parameters:
        series - the series (zero-based index).
        item - the item (zero-based index).
        Returns:
        A Number representing the maximum non-farout value.
      • getMaxOutlier

        Number getMaxOutlier(int series,                   int item)
        Returns the maximum value which is not a farout, ie Q3 + (interquartile range * farout coefficient).
        Parameters:
        series - the series (zero-based index).
        item - the item (zero-based index).
        Returns:
        A Number representing the maximum non-farout value.
      • getOutliers

        List getOutliers(int series,               int item)
        Returns a list of outliers for the specified series and item.
        Parameters:
        series - the series (zero-based index).
        item - the item (zero-based index).
        Returns:
        The list of outliers for the specified series and item (possibly null).
      • getOutlierCoefficient

        double getOutlierCoefficient()
        Returns the value used as the outlier coefficient. The outlier coefficient gives an indication of the degree of certainty in an unskewed distribution. Increasing the coefficient increases the number of values included. Currently only used to ensure farout coefficient is greater than the outlier coefficient
        Returns:
        A double representing the value used to calculate outliers
      • getFaroutCoefficient

        double getFaroutCoefficient()
        Returns the value used as the farout coefficient. The farout coefficient allows the calculation of which values will be off the graph.
        Returns:
        A double representing the value used to calculate farouts
