Detailed Description

Interface for iterating over an array of samples.

Constructor & Destructor Documentation

QwtSetSeriesData::QwtSetSeriesData ( const QVector< QwtSetSample > &  samples = QVector<QwtSetSample>())

Constructor

Parameters
samplesSamples

Member Function Documentation

QRectF QwtSetSeriesData::boundingRect ( ) const
virtual

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< QwtSetSample >.
