QPolarChart::QPolarChart(QGraphicsItem *parent = Q_NULLPTR, Qt::WindowFlags wFlags = Qt::WindowFlags())

Constructs a polar chart as a child of the parent. Parameter wFlags is passed to the QChart constructor.

QPolarChart::~QPolarChart()

Destroys the polar chart object and its children, like series and axis objects added to it.

void QPolarChart::addAxis(QAbstractAxis *axis, PolarOrientation polarOrientation)

This convenience method adds axis to the polar chart with polarOrientation. The chart takes the ownership of the axis.

Note: Axes can be added to a polar chart also with QChart::addAxis() instead of this method. The specified alignment determines the polar orientation: horizontal alignments indicate angular axis and vertical alignments indicate radial axis.

See also QChart::removeAxis(), QChart::createDefaultAxes(), QAbstractSeries::attachAxis(), and QChart::addAxis().

QList<QAbstractAxis *> QPolarChart::axes(PolarOrientations polarOrientation = PolarOrientations( PolarOrientationRadial | PolarOrientationAngular ), QAbstractSeries *series = Q_NULLPTR) const

Returns the axes added for the series with polarOrientation. If no series is provided, then any axis with the specified polar orientation is returned.

See also addAxis().

[static] PolarOrientation QPolarChart::axisPolarOrientation(QAbstractAxis *axis)

Angular axes of a polar chart report horizontal orientation and radial axes report vertical orientation. This function is a convenience function for converting the orientation of an axis to corresponding polar orientation. If the axis is NULL or not added to a polar chart, the return value is meaningless.
