How to set legendbox position by passing variable?

KC

Hi,

I want to set  LegendBox position by a list  as following jsl, but it is not work. how do I pass the "mylist " into position?

the list "mylist" will be  a dynamic result from other funciton , so I need to pass the variable  while setup graph builder  or update the graph builder after announcement.

I need the graph legendbox like the picture.  

 

 

Names Default To Here( 1 );
Open( "$SAMPLE_DATA/Big Class.jmp" );
gb = Graph Builder(
	Show Control Panel( 0 ),
	Variables(
		X( :height ),
		Y( :weight ),
		Overlay( :sex )
	),
	Elements(
		Points( X, Y, Legend( 0 ) ),
		Smoother( X, Y, Legend( 1 ) )
	)
);

mylist={-1, -1, 1, 0};

Report( gb )[LegendBox( 1 )] << Position(mylist );

The Position Message apparently does not support evaluation prior to its execution, therefore by using the Substitute() function you can force the evaluation.

Names Default To Here( 1 );
Open( "$SAMPLE_DATA/Big Class.jmp" );
gb = Graph Builder(
	Show Control Panel( 0 ),
	Variables( X( :height ), Y( :weight ), Overlay( :sex ) ),
	Elements(
		Points( X, Y, Legend( 0 ) ),
		Smoother( X, Y, Legend( 1 ) )
	)
);

mylist = {-1, -1, 1, 0};
Eval(
	Substitute(
			Expr(
				Report( gb )[LegendBox( 1 )] << Position( __myList__ )
			),
		Expr( __myList__ ), myList
	)
);
