Constructor & Destructor Documentation
- QwtCPointerData::QwtCPointerData (const double * x, const double * y,
- size_t size)
Constructor - Warning:
The programmer must assure that the memory blocks referenced by the pointers remain valid during the lifetime of the QwtPlotCPointer
object. - See also:
QwtCurve::setRawData and QwtPlot::setCurveRawData.

Member Function Documentation
- QwtDoubleRect QwtCPointerData::boundingRect () const [virtual]
- 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 from QwtData.

- References size().
- QwtData * QwtCPointerData::copy () const [virtual]
- Return a pointer to a copy (virtual copy constructor)
- Implements QwtData.

- double QwtCPointerData::x (size_t i) const [virtual]
- Return the x value of data point i
- Parameters:
