SYNOPSIS
       #include <qwt_interval_data.h>

   Public Member Functions
       QwtIntervalData ()
       QwtIntervalData (const QwtArray< QwtDoubleInterval > &, const QwtArray<
	   double > &)
       ~QwtIntervalData ()

Detailed Description
       Series of samples of a value and an interval.

       QwtIntervalData is a series of samples of a value and an interval. F.e.
       error bars are built from samples [x, y1-y2], while a histogram might
       consist of [x1-x2, y] samples.

Member Function Documentation
   QwtDoubleRect QwtIntervalData::boundingRect () const
       Calculate the bounding rectangle of the samples

       The x coordinates of the rectangle are built from the intervals, the y
       coordinates from the values.

       Returns:
	   Bounding rectangle

   const QwtDoubleInterval & QwtIntervalData::interval (size_ti) const
       [inline]
       Interval of a sample

       Parameters:
	   i Sample index

       Returns:
	   Interval

       See also:
	   value(), size()

   size_t QwtIntervalData::size () const [inline]
       Returns:
	   Number of samples

   double QwtIntervalData::value (size_ti) const [inline]
       Value of a sample

       Parameters:
	   i Sample index

       Returns:
	   Value

       See also:
	   interval(), size()
