This attribute functions only on the X axis. If the value is 1, a scrollbar appears that scrolls the X axis. If the value is 0, no scrollbar appears. If the operator scrolls the window away from the leading edge (the point where new data is being added to the chart), the data in the window stops scrolling and the window stays in the same location over the data. Later, if the operator scrolls back to the leading edge of the data, the data again starts scrolling in the window.
