| QRectF DataSeriesBase::boundingRect | ( | ) | const [inline, override, virtual] |
Calculate the bounding rect of all samples
The bounding rect is necessary for autoscaling and can be used for a couple of painting optimizations.
qwtBoundingRect(...) offers slow implementations iterating over the samples. For large sets it is recommended to implement something faster f.e. by caching the bounding rectangle.
- Returns:
- Bounding rectangle
Implements QwtSeriesData< QPointF >.
