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.
Constructor & Destructor Documentation
QwtIntervalData::QwtIntervalData ()
Constructor.
QwtIntervalData::QwtIntervalData (const QwtArray< QwtDoubleInterval >
&intervals, const QwtArray< double > &values)
Constructor.
QwtIntervalData::~QwtIntervalData ()
Destructor.
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

void QwtIntervalData::setData (const QwtArray< QwtDoubleInterval >
&intervals, const QwtArray< double > &values)
Assign samples.
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
