Interface ScrollModelInterface

public interface ScrollModelInterface

ScrollModelInterface consolidates properties associated with the scrollbars that can appear on interactive charts when the graph matrix is too large to display in the available chart component area.

Usage

This class will not be directly used by a client, but setting other properties (for example DISPLAY_FIT_TO_SCREEN as the displayType on the GraphModel) will affect the ScrollModelInterface.

Behavior

Whether to allow scroll bars or not, as well as the scroll bar(s) exact position in the Graph component is maintained by the ScrollModelInterface.

Since:

SAS 9.1
