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.
| 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.
