Member Function Documentation
| QRectF QwtPointArrayData::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< QPointF >.
Definition at line 55 of file qwt_point_data.cpp.
| QPointF QwtPointArrayData::sample | ( | size_t | index | ) | const [virtual] |
Return the sample at position i
- Parameters:
-
index Index
- Returns:
- Sample at position i
Implements QwtSeriesData< QPointF >.
Definition at line 75 of file qwt_point_data.cpp.
| size_t QwtPointArrayData::size | ( | ) | const [virtual] |
- Returns:
- Size of the data set
Implements QwtSeriesData< QPointF >.
Definition at line 64 of file qwt_point_data.cpp.
| const QVector< double > & QwtPointArrayData::xData | ( | ) | const |
- Returns:
- Array of the x-values
Definition at line 81 of file qwt_point_data.cpp.
| const QVector< double > & QwtPointArrayData::yData | ( | ) | const |
- Returns:
- Array of the y-values
