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);
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.
