QwtData defines an interface to any type of curve data.
Classes, derived from QwtData may:
QwtData::QwtData | ( | ) |
Constructor.
QwtData::~QwtData | ( | ) | [virtual] |
Destructor.
QwtDoubleRect QwtData::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
