    \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().
