How can I output the graph in the same window as the button?

[#1]

When I write the command to output the graph in the button, it actually outputs in a new window. What should I do to output the graph in the same window (as shown in the figure below)?

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
nw2 = New Window( "New window",
	outputG = Button Box( "Output Graph",
		Outline Box( "Graph Output", 
		Bivariate( y( :weight ), x( :height ) ); )
	)
);

You could collect them into some display element

Names Default To Here(1);
dt = Open("$SAMPLE_DATA/Big Class.jmp");
nw2 = New Window("New window",
	outputG = Button Box("Output Graph",
		vlb << Append(Outline Box("Graph Output", Bivariate(y(:weight), x(:height))))
	),
	vlb = V List Box()
);

The objects created when the button box is clicked need to be appended back to the window.

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
nw2 = New Window( "New window",
	outputG = Button Box( "Output Graph",
		ob = Outline Box( "Graph Output",
			Bivariate( y( :weight ), x( :height ) )
		);
		nw2 << append( ob );
	)
);
