This attribute, when set to 1, enables the BARS area of the widget to scroll. If a combination of BAR COUNT, BAR WIDTH, and BAR SEPARATION is greater than the BARS area, a scrollbar appears. Use the scrollbar to scroll the desired bar into view.
Scrolling occurs in increments of pixels or bars as determined by the SCROLL INCREMENT attribute. Only the bars and their labels scroll - the limits labels remain stationary. SCROLLABLE and AUTOPOSITION are mutually exclusive - setting one turns off the other.
