BoxSet represents one box-and-whiskers item. It takes five values to create a graphical representation
|
|
|
of range and three medians. There are two ways to give the values. The first one is with constructor
|
|
|
or with append method. In these the values have to be given in the following order: lower extreme, lower quartile, median,
|
|
|
upper quartile and upper extreme. The second method is to create an empty QBoxSet instance and give the values using
|
|
|
value specific methods.

BoxPlotSeries represents a series of data shown as box-and-whiskers bars. The purpose of this class is to act as
|
|
|
a container for single box-and-whiskers items. Each item is drawn to own slot. If chart includes multiple instances of
|
|
|
BoxPlotSeries then box-and-whiskers items with the same index are drawn to same slot.
|
|
|
|
|
|
The following QML shows how to create a simple box-and-whiskers chart:
