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.

  QwtData * QwtArrayData::copy () const [virtual] Returns:
    Pointer to a copy (virtual copy constructor)

Implements QwtData.

  QwtArrayData & QwtArrayData::operator= (const QwtArrayData &data)

Assignment.

  size_t QwtArrayData::size () const [virtual] Returns:
    Size of the data set

Implements QwtData.

  double QwtArrayData::x (size_ti) const [virtual] Return the x value of data point i

Parameters:
    i Index

Returns:
    x X value of data point i

Implements QwtData.

  const QwtArray< double > & QwtArrayData::xData () const Returns:
    Array of the x-values

  double QwtArrayData::y (size_ti) const [virtual] Return the y value of data point i

Parameters:
    i Index

Returns:
    y Y value of data point i

Implements QwtData.

  const QwtArray< double > & QwtArrayData::yData () const Returns:
    Array of the y-values
