SYNOPSIS

#include <qwt_interval_data.h> Public Member Functions QwtIntervalData () QwtIntervalData (const QwtArray< QwtDoubleInterval > &, const QwtArray< double > &) ~QwtIntervalData () QwtDoubleRect boundingRect () const const QwtDoubleInterval & interval (size_t i) const void setData (const QwtArray< QwtDoubleInterval > &, const QwtArray< double > &) size_t size () const double value (size_t i) const 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() Author Generated automatically by Doxygen for Qwt User's Guide from the source code.
