## Properties

- axisX : QAbstractAxis*
- axisY : QAbstractAxis*

## Public Functions

| QBarSeries(QObject *parent = nullptr)
virtual | ~QBarSeries()
QAbstractAxis * | axisX()
QAbstractAxis * | axisY()
void | setAxisX(QAbstractAxis *axis)
void | setAxisY(QAbstractAxis *axis)

## Reimplemented Public Functions

## Detailed Description

This class draws data as a series of vertical bars grouped by category, with one bar per category from each bar set added to the series.

See also QBarSet and QAbstractBarSeries.

## Property Documentation

### axisX : QAbstractAxis*

X-axis of the series.

The x-axis used for the series. This should be QBarCategoryAxis.

Access functions:

QAbstractAxis * | axisX()
void | setAxisX(QAbstractAxis *axis)

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:

QAbstractAxis * | axisY()
void | setAxisY(QAbstractAxis *axis)

Notifier signal:

void | axisYChanged(QAbstractAxis *axis)

## 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.
