Abstract: A method for determining an interval via a graphical user interface includes displaying a navigation bar. The navigation bar has a scale and a slider. The slider is configured to be movable along the scale. The scale has two handles on end faces of the slider opposite to each other longitudinally to the scale. The method further includes retaining opposite handle and adjusting the slider on the side of the dragged handle if one of the handles is dragged. The method further includes dividing the navigation bar into a core area having the slider and two edge areas if the slider falls below a predefined minimum length. The edge areas extend to both sides of the core area longitudinally to the scale and expand the scale and the slider within the core area and compressing the scale in the edge areas.
