Member Function Documentation

QRectF DataSeriesBase::boundingRect ( ) const

inlineoverridevirtual

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 >.
