Methods
Detailed Description
A box-and-whiskers item is a graphical representation of a range and three median values that is constructed from five different values. There are two ways to specify the values. The first one is by using a constructor or the append() method. The values have to be specified in the following order: lower extreme, lower quartile, median, upper quartile, and upper extreme.
The second way is to create an empty BoxSet instance and specify the values using the setValue() method.
See also BoxPlotSeries.
