Member Function Documentation
- QwtDoubleRect QwtArrayData::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 * QwtArrayData::copy () const [virtual]
- Return a pointer to a copy (virtual copy constructor)
- Implements QwtData.

- double QwtArrayData::x (size_t i) const [virtual]
- Return the x value of data point i
- Parameters:
i Index
- Returns:
x X value of data point i
