## Member Function Documentation

## boundingRect()

QRectF QwtVectorFieldData::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< T >.
