QRectF QwtPoint3DSeriesData::boundingRect | ( | ) | const [virtual] |
Calculate the bounding rect.
The bounding rectangle is calculated once by iterating over all points and is stored for all following requests.
Implements QwtSeriesData< QwtPoint3D >.
virtual QwtPoint3D QwtArraySeriesData< QwtPoint3D >::sample | ( | size_t | i | ) | const [virtual, inherited] |
Return a sample
i | Index |
Implements QwtSeriesData< QwtPoint3D >.
virtual size_t QwtArraySeriesData< QwtPoint3D >::size | ( | ) | const [virtual, inherited] |
Implements QwtSeriesData< QwtPoint3D >.
QRectF QwtSeriesData< QwtPoint3D >::d_boundingRect [mutable, protected, inherited] |
Can be used to cache a calculated bounding rectangle.
QVector<QwtPoint3D > QwtArraySeriesData< QwtPoint3D >::d_samples [protected, inherited] |
Vector of samples.
