A drawing primitive for displaying an interval like an error bar.
Symbol style.
| 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. |
