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