\class QBoxPlotSeries
\brief Series for creating box-and-whiskers chart
\mainclass
QBoxPlotSeries represents a series of data shown as box-and-whisker bars. The purpose of this class is to act as
a container for single box-and-whisker items. Each item is drawn to own slot. If chart includes multiple instances of
QBoxPlotSeries then box-and-whiskers items with the same index are drawn to same slot.
See the \l {Box and Whiskers Example} {box-and-whiskers chart example} to learn how to create a box-and-whiskers chart.

\inherits QAbstractSeries
BoxPlotSeries represents a series of data shown as box-and-whisker bars. The purpose of this class is to act as
a container for single box-and-whisker 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:
\code
