How can I move the x-axis on top of graph?

[#1]

Hi, I'm trying to create a trace element concentration profile and need to have the x-axis (concentrations) at the top of the graph so that it can show how the concentration varies down-core .. Is there any way to do this?

If you run this script:

NamesDefaultToHere(1);
dt = Open("$SAMPLE_DATA/Big Class.jmp");
gb = dt << Graph Builder(
	Size( 528, 452 ),
	Show Control Panel( 0 ),
	Variables( X( :weight ), Y( :height ) ),
	Elements( Points( X, Y, Legend( 6 ) ) ),
	SendToReport(
		Dispatch(
			{},
			"weight",
			ScaleBox,
			{Label Row(
				{Inside Ticks( 1 ), Show Major Grid( 1 ), Show Minor Grid( 1 ),
				Show Minor Labels( 1 )}
			)}
		)
	)
);

it produces:

(which you could make interactively, of course).

I then did 'Edit > Journal' to make a Journal file, then used the 'fat plus' tool to move elements around to make:

Finally we discover a reason why we might want to select the axes in isolation from the graph :)
