Detailed Description
The QSplineSeries class presents data as spline charts.
A spline series stores the data points and the segment control points needed by QPainterPath to draw a spline. The control points are automatically calculated when the data changes. The algorithm computes the points so that the normal spline can be drawn.
The following code snippet illustrates how to create a basic spline chart:
QSplineSeries* series = new QSplineSeries(); series->append(0, 6); series->append(2, 4); ... chart->addSeries(series);
Member Function Documentation
QSplineSeries::QSplineSeries(QObject *parent = nullptr)
Constructs an empty series object that is a child of parent. When the series object is added to a QChart instance, the ownerships is transferred.
[virtual] QSplineSeries::~QSplineSeries()
Deletes the spline series.
[virtual] QAbstractSeries::SeriesType QSplineSeries::type() const
Reimplemented from QLineSeries::type().
