The median is indicated by the line inside the box, * while the mean is at the center of the filled circle inside the box. * Define the interquartile range as (<SPAN CLASS="MATH"><I>Q</I><SUB>3</SUB> - <I>Q</I><SUB>1</SUB></SPAN>). * Any data observation which is more than * <SPAN CLASS="MATH">1.5(<I>Q</I><SUB>3</SUB> - <I>Q</I><SUB>1</SUB>)</SPAN> lower than the first * quartile or * <SPAN CLASS="MATH">1.5(<I>Q</I><SUB>3</SUB> - <I>Q</I><SUB>1</SUB>)</SPAN> higher than the third quartile is considered an * outlier. The smallest and the largest values that are not outliers are connected * to the box with a vertical line or "whisker" which is ended by a horizontal line. * Outliers are indicated by hollow circles outside the whiskers. Triangles * indicate the existence of very far outliers. * */ public class BoxChartAdapter extends CategoryChart { /** * Modified Method: set visible to be false * * Displays chart on the screen using Swing. * This method creates an application containing a chart panel displaying * the chart.
