ABSTRACT:
A graphical user interface displays a coarse control scrollbar to provide a user with coarse resolution sequential data control and a magnified view scrollbar proximate to the coarse control scrollbar. The magnified view scrollbar provides the user with fine resolution sequential data control. When the cursor is on the scrollbar, an overlay is opened which is a zoomed version of the scrollbar. The zoom range of the overlay is adjustable and can either be preset by the user or set during the zooming operation. When operating the overlay, a menu is available which allows the user to choose between zooming up or down to select the desired position.
