Member Function Documentation

boundingRect()

QRectF QwtPointSeriesData::boundingRect ( ) const

overridevirtual

Calculate the bounding rectangle.

The bounding rectangle is calculated once by iterating over all points and is stored for all following requests.

Returns

Bounding rectangle

Implements QwtSeriesData< QPointF >.

Reimplemented in QwtSyntheticPointData.
