Description

This X-Function adds an axis scrollbar to a graph layer, allowing user to zoom and pan the layer easily.

The axis scrollbar is comprised of a scroll box and a scroll area. The scroll box can be resized and moved. The ratio of its size to the size of the whole scrollbar reflects the ratio of the current range to the full range. To zoom in the layer, make this scroll box larger; to zoom out, make it smaller. The relative position of the scroll box reflects the initial value and the final value of the scale. Therefore, you can move this scroll box so as to pan the layer.
