Detailed Description
Series type used to store data needed to draw a spline.
QSplineSeries stores the data points along with the segment control points needed by QPainterPath to draw spline Control points are automatically calculated when data changes. The algorithm computes the points so that the normal spline can be drawn.
Creating basic spline chart is simple:
QSplineSeries* series = new QSplineSeries(); series->append(0, 6); series->append(2, 4); ... chart->addSeries(series);
Member Function Documentation
QSplineSeries::QSplineSeries(QObject *parent = Q_NULLPTR)
Constructs empty series object which is a child of parent. When series object is added to a QChart instance then the ownerships is transferred.
QSplineSeries::~QSplineSeries()
Destroys the object.
[virtual] QAbstractSeries::SeriesType QSplineSeries::type() const
Reimplemented from QAbstractSeries::type().
Returns the type of the series
