\class QCandlestickModelMapper
\since 5.8
\inmodule QtCharts
\brief Abstract model mapper class for candlestick series.
Model mappers allow the use of a QAbstractItemModel-derived model as a data source for a chart
series, creating a connection between a QCandlestickSeries and the model object. A model mapper
maintains an equal size across all \l {QCandlestickSet} {QCandlestickSets}.
\note The model used must support adding and removing rows/columns and modifying the data of the
cells.

\class QCandlestickSeries
\since 5.8
\inmodule QtCharts
\brief The QCandlestickSeries class presents data as candlesticks.
This class acts as a container for single candlestick items. Each item is drawn to its own category
when using QBarCategoryAxis. QDateTimeAxis and QValueAxis can be used as alternatives to
QBarCategoryAxis. In this case, each candlestick item is drawn according to its timestamp value.
\note The timestamps must be unique within a QCandlestickSeries. When using QBarCategoryAxis,
only the first one of the candlestick items sharing a timestamp is drawn. If the chart includes
multiple instances of QCandlestickSeries, items from different series sharing a timestamp are
drawn to the same category. When using QValueAxis or QDateTimeAxis, candlestick items sharing a
timestamp will overlap each other.
See the \l {Charts with Widgets Gallery} to learn how to create
a candlestick chart.

\class QCandlestickSet
\since 5.8
\inmodule QtCharts
\brief The QCandlestickSet class represents a single candlestick item in a
candlestick chart.
Five values are needed to create a graphical representation of a candlestick
item: \e open, \e high, \e low, \e close, and \e timestamp. These values can
be either passed to a QCandlestickSet constructor
or set by using setOpen(), setHigh(), setLow(), setClose(), and setTimestamp().

\class QHCandlestickModelMapper
\since 5.8
\inmodule QtCharts
\brief The QHCandlestickModelMapper class is a horizontal model mapper for a candlestick 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 QCandlestickSeries, so that each row in the data model defines a
candlestick item and each column maps to the open, high, low, close, and timestamp values
of the candlestick item.
Both model and candlestick series properties can be used to manipulate the data. The model
mapper keeps the candlestick series and the data model in sync.
The model mapper ensures that all the candlestick items in the candlestick series have equal
sizes. Therefore, adding or removing a value from a candlestick item causes the same change to
be made in all the candlestick items in the candlestick series.
