Capturing selections made by a user using the local data filter in Graph Builder

[#1]

I would like to be able to capture the selection made when a user selects a value using the local data filter for a Graph Builder object.

For example in the snippet below, if I selected "Apple" using the local data filter, how do I capture "Apple" in a variable so I can put it in a chart title.

Does this require the use of the row state handler? I have not used that before.  Thank you! -Jens

NamesDefaultToHere(1);
Clear Log();

// Some data
dt = New Table ( "Fruits", Add Rows( 3 ),
     New Column( "Fruit" , Character, "Nominal", Set Values( {"Pear", "Apple", "Orange"} ))
);

// A report with a local data filter
gb = dt << Graph Builder(Size( 528, 448 ),Show Control Panel( 0 ),Show Legend( 0 ),
     Variables( X  ( :Fruit ) ),
     Elements ( Bar( X, Legend( 3 ) ) ),
     Local Data Filter( Mode, Add Filter( columns( :Fruit ) ) )
);

// want to capture value of Local Data Filter selection into a variable
ldf_selection = ???

Here is the entry from the Scripting Index that shows how to return the Where Clause used in the seleeellll

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Cities.jmp" );
obj = dt <<
local Data Filter(
	Add( Filter Columns( :Region, :Lead ) )
);
Wait( 1 );
obj << (Filter Column( :Lead ) <<
Where( :Lead >= .4 & :Lead <= 1.4 ));
txt = obj << get where clause;
