    • DefaultBoxAndWhiskerXYDataset

      Constructs a new box and whisker dataset.

  • Method Details

    • getOutlierCoefficient

      public 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
      Specified by:
      getOutlierCoefficient in interface BoxAndWhiskerXYDataset
      Returns:
      A double representing the value used to calculate outliers.
      See Also:
    • setOutlierCoefficient

      public void setOutlierCoefficient(double outlierCoefficient)
      Sets the value used as the outlier coefficient
      Parameters:
      outlierCoefficient - being a double representing the value used to calculate outliers.
      See Also:
    • getFaroutCoefficient

      public double getFaroutCoefficient()
      Returns the value used as the farout coefficient. The farout coefficient allows the calculation of which values will be off the graph.
      Specified by:
      getFaroutCoefficient in interface BoxAndWhiskerXYDataset
      Returns:
      A double representing the value used to calculate farouts.
      See Also:
    • setFaroutCoefficient

      public void setFaroutCoefficient(double faroutCoefficient)
      Sets the value used as the farouts coefficient. The farout coefficient must b greater than the outlier coefficient.
      Parameters:
      faroutCoefficient - being a double representing the value used to calculate farouts.
