Detailed Description

This class represent interval between two values and is usually used for specification of axis scale. It can fire event to listeners, when is changed.

Constructor & Destructor Documentation

com::cosylab::gui::components::r2::chart::Interval::Interval ( ) [inline]

Interval constructor.

com::cosylab::gui::components::r2::chart::Interval::Interval	(	double	min,
		double	max
	)			`[inline]`

Interval constructor, which takes as an argument minimal and maximal value of interval.
