## ◆ QwtPoint3DSeriesData()

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

Constructor

Parameters

  samples | Samples

## Member Function Documentation

## ◆ boundingRect()

QRectF QwtPoint3DSeriesData::boundingRect | ( |  | ) | const

override 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< T >.
