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.

   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
