Detailed Description

Interface for iterating over an array of 3D points.

Constructor & Destructor Documentation

QwtPoint3DSeriesData::QwtPoint3DSeriesData ( const QVector< QwtPoint3D > &  samples = QVector<QwtPoint3D>())



Member Function Documentation

QRectF QwtPoint3DSeriesData::boundingRect ( ) const

Calculate the bounding rectangle.

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

Bounding rectangle
