Syntax

CALL NOTIFY (graph-output-name, '_hscroll', <unit<, num-units>>);

Argument Type Description

'MAX '

'PAGE'

'HALF'

'COLUMN'

num-units
N specifies the number of units to scroll. To scroll right, specify a positive number; to scroll left, specify a negative number. The default is 1

Argument	Type	Description
	C	specifies the scrolling unit:
		'MAX '
		'PAGE'
		'HALF'
		'COLUMN'
num-units	N	specifies the number of units to scroll. To scroll right, specify a positive number; to scroll left, specify a negative number. The default is 1

Details

The _hscroll method is useful when the graphics output is not scaled to fit the region and a large graph, or multiple graphs, may be partially hidden. You can use the _hscroll method to scroll graphics output whether or not the scroll bars are turned on.

This method is useful for switching between multiple pictures rendered into the same GRSEG entry. For example, if you use the GREPLAY procedure to create a template containing four graphs and you bring the templated graph into the SAS/GRAPH output object, use _hscroll to scroll from one graph to another.

Example

This example shows different ways of scrolling a graph horizontally:

   /* scroll all the way right */
call notify('graph1', '_hscroll_', 'max',
             1);


   /* scroll left one page */
call notify('graph1, '_hscroll_', 'page',
            -1);
                  '
   /* scroll right one page */
call notify('graph1', '_hscroll_', 'page',
             1);

   /* scroll left one column */
call notify('graph1', '_hscroll_', 'column',

            -1);

   /* scroll right one column */
call notify('graph1', '_hscroll_', 'column',
             1);
