Notifier signal:

void axisXChanged(QAbstractAxis *axis)

axisY : QAbstractAxis*

Y-axis of the series.

The y-axis used for the series. This should be QValueAxis.

Access functions:

Member Function Documentation

[explicit] QBarSeries::QBarSeries(QObject *parent = nullptr)

Constructs an empty bar series that is a QObject and a child of parent.

[virtual noexcept] QBarSeries::~QBarSeries()

Removes the bar series from the graph.

[override virtual] QAbstractSeries::SeriesType QBarSeries::type() const

Reimplements an access function for property: QAbstractSeries::type.

Returns the bar series.
