\brief QwtPlotIntervalCurve represents a series of samples, where each value
is associated with an interval ( \f$[y1,y2] = f(x)\f$ ).
The representation depends on the style() and an optional symbol()
that is displayed for each interval. QwtPlotIntervalCurve might be used
to disply error bars or the area between 2 curves.
