Syntax

CALL NOTIFY (graph-output-name, '_addHotspot', list-id);

Argument Type Description

list-id
N specifies the identifier for an SCL list containing the hotspot attributes described in the following table:

Argument	Type	Description
list-id	N	specifies the identifier for an SCL list containing the hotspot attributes described in the following table:

List item Type Description

COLOR C the color of the hotspot

FILLTYPE N the fill style of the highlight:

1 empty (outline only)

2 filled

NAME C the name of the segment hotspot

SPOTID N the number of the graph segment where the hotspot is located

List item	Type	Description
COLOR	C	the color of the hotspot
FILLTYPE	N	the fill style of the highlight:
		1	empty (outline only)
		2	filled
NAME	C	the name of the segment hotspot
SPOTID	N	the number of the graph segment where the hotspot is located

Details

The list passed to the _addHotspot method must be explicitly created and filled using SCL list functions in the SCL program.
_addHotspot can dynamically add a hotspot to the output object at run time. The hotspot is visible when it is added.
To find the number of a graph segment, invoke the _getInfo method and retrieve the value returned in the SPOTID list item. You can use this number to position the hotspot by passing the value to the SPOTID item in the SCL list used by the _addHotspot method.

Example

This example creates an SCL list ATTRLIST and fills it with the attributes of a blue outline hotspot named HOT2, which is to be assigned to graph segment 5. The _addHotspot method adds the hotspot to GRAPH1.

attrlist = makelist();
setnitemc(attrlist, 'hot2', 'name');
setnitemc(attrlist, 'blue', 'color');
setnitemn(attrlist, 1, 'filltype');
setnitemn(attrlist, 5, 'spotid');
call notify('graph1','_add_hotspot_',
             attrlist);
