In such case series don't draw a direct line between - the two points, but instead draw a line to and from the center of the chart. - - \note Polar charts draw all axes of same orientation in the same position, so using multiple - axes of same orientation can be confusing, unless the extra axes are only used to customize the - grid (e.g. you can display a highlighted range with a secondary shaded QCategoryAxis or provide - unlabeled subticks with a secondary QValueAxis that has its labels hidden). - - \sa QChart - */ - -/*! - Constructs a polar chart as a child of the \a parent. - Parameter \a wFlags is passed to the QChart constructor. - */ -QPolarChart::QPolarChart(QGraphicsItem *parent, Qt::WindowFlags wFlags) - : QChart(QChart::ChartTypePolar, parent, wFlags) -{ -} - -/*! - Destroys the polar chart object and its children, like series and axis objects added to it. - */ -QPolarChart::~QPolarChart() -{ -} - -/*! - Returns the axes added for the \a series with \a polarOrientation.
