Returns the bounding rectangle of the data. If there is no bounding rect, like for empty data the rectangle is invalid: QwtDoubleRect::isValid() == FALSE
Reimplemented in QwtArrayData, and QwtCPointerData. Definition at line 33 of file qwt_data.cpp. References size(), x(), and y(). Referenced by QwtCurve::boundingRect(). |

Return a pointer to a copy (virtual copy constructor) Implemented in QwtDoublePointData, QwtArrayData, and QwtCPointerData.
Referenced by QwtCurve::copy(), and QwtCurve::setData(). |
