Detailed Description

A drawing primitive for displaying an interval like an error bar.

Member Enumeration Documentation

◆ Style

enum QwtIntervalSymbol::Style

Symbol style

Enumerator
NoSymbol	No Style. The symbol cannot be drawn.
Bar	The symbol displays a line with caps at the beginning/end. The size of the caps depends on the symbol width().
Box	The symbol displays a plain rectangle using pen() and brush(). The size of the rectangle depends on the translated interval and the width().
UserSymbol	Styles >= UserSymbol are reserved for derived classes of QwtIntervalSymbol that overload draw() with additional application specific symbol types.
