|
|
|
\brief 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:
|
|
|
\code
|
|
|
QSplineSeries* series = new QSplineSeries();
|
|
|
series->append(0, 6);
|
|
|
series->append(2, 4);
|
|
|
...
|
|
|
chart->addSeries(series);
|
|
|
\endcode
