\class QVCandlestickModelMapper

\inmodule Qt Charts
\brief Vertical model mapper for a 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 vertical
model mapper maintains an equal size across all \l {QCandlestickSet} {QCandlestickSets}, and
reads the values of the set from the model's columns.
\note The model used must support adding and removing rows/columns and modifying the data of the
cells.

\inqmlmodule QtCharts
\brief Vertical model mapper for a candlestick series.
VCandlestickModelMapper allows the use of a QAbstractItemModel-derived model with data in
columns as a data source for a candlestick series. It's possible to manipulate the data either
through QAbstractItemModel or QCandlestickSeries.
The following QML example creates a candlestick series with three candlestick sets (assuming the
model has at least four columns). Each candlestick set would contain data defined by timestamp,
open, high, low and close rows. The name of a set would be defined by the horizontal header of
the column.
\qml
CandlestickSeries {
VCandlestickModelMapper {
model: myCustomModel // QAbstractItemModel derived implementation
timestampRow: 1
openRow: 2
highRow: 3
lowRow: 4
closeRow: 5
firstCandlestickSetColumn: 1
lastCandlestickSetColumn: 3
}
}
\endqml
\note VCandlestickModelMapper keeps the series and the model in sync.
