\class QBoxPlotModelMapper
\inmodule QtCharts
\brief The QBoxPlotModelMapper class is the base class for box plot model
mapper classes.
\internal
Model mappers enable using a data model derived from the QAbstractItemModel
class as a data source for a chart.

\class QBoxPlotSeries
\inmodule QtCharts
\brief The QBoxPlotSeries class presents data in box-and-whiskers charts.
A box plot series acts as a container for box-and-whiskers items. Items from multiple series
are grouped into categories according to their index value.
The QBarCategoryAxis class is used to add the categories to the chart's axis. Category labels
have to be unique. If the same category label is defined for several box-and-whiskers items,
only the first one is drawn.
See the \l {Charts with Widgets Gallery} to learn how to create a
box-and-whiskers chart.

\class QBoxSet
\inmodule QtCharts
\brief The QBoxSet class represents one item in a box-and-whiskers chart.
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 stream operator (<<). 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 QBoxSet instance and specify the values using the
setValue() method.
See the \l{Charts with Widgets Gallery} to learn how to
create a box-and-whiskers chart.

\class QHBoxPlotModelMapper
\inmodule QtCharts
\brief The QHBoxPlotModelMapper class is a horizontal model mapper for box
plot series.
Model mappers enable using a data model derived from the QAbstractItemModel
class as a data source for a chart. A horizontal model mapper is used to
create a connection between a data model and QBoxPlotSeries object, so that
each row in the data model defines a box-and-whiskers item and each column
maps to the range and three median values of the box-and-whiskers item.
Both model and series properties can be used to manipulate the
data. The model mapper keeps the series and the data model in sync.
The model mapper ensures that all the box-and-whiskers items in the box plot
series have equal sizes. Therefore, adding or removing a value from a
box-and-whiskers item causes the same change to be made in all the
box-and-whiskers items in the box plot series.

\class QVBoxPlotModelMapper
\inmodule QtCharts
\brief The QVBoxPlotModelMapper is a vertical model mapper for box plot
series.
Model mappers enable using a data model derived from the QAbstractItemModel class
as a data source for a chart. A vertical model mapper is used to create a connection
between a data model and a QBoxPlotSeries object, so that each column in the data model
defines a box-and-whiskers item and each row maps to the range and three median
values of the box-and-whiskers item.
Both model and series properties can be used to manipulate the data. The model mapper
keeps the series and the data model in sync.
The model mapper ensures that all the bar box-and-whiskers items in the box plot
series have equal sizes. Therefore, adding or removing a value from a box-and-whiskers
item causes the same change to be made in all the box-and-whiskers items in the
box plot series.
