     The QChart class provides two methods that map between the scene coordinates and the series domain
    (defined by the axes ranges).

     QPointF QChart::mapToPosition(const QPointF &value, QAbstractSeries *series)

     QPointF QChart::mapToValue(const QPointF &position, QAbstractSeries *series)
