Change graph background colour between reference lines

Question

Hi, I have a scatter plot with a line of best fit to which I've added 2 reference lines to the x-axis.

Is there an easy way of changing the background of the area between both reference lines to light-grey.

Thanks!

One option is to use some scripting and add graphic script

Names Default To Here(1);

dt = Open("$SAMPLE_DATA/Big Class.jmp");

gb = dt << Graph Builder(
	Variables(X(:weight), Y(:height)),
	Elements(Points(X, Y, Legend(3))),
	SendToReport(
		Dispatch(
			{},
			"height",
			ScaleBox,
			{Add Ref Line(65, "Solid", "Black", "", 1),
			Add Ref Line(55, "Solid", "Black", "", 1)}
		)
	)
);

rep = gb << report;
framebox = rep[frame box(1)];
framebox << Add Graphics Script(
	Transparency(0.5);
	Fill Color("Gray");
	Rect(X Origin(), 65, X Origin() + X Range(), 55, 1)
);
