Spec Limits line not showing in Fit Curve Platform

JaredJ — Sun, 11 Jun 2023 11:16:40 GMT

Hi all,

I have loaded & saved the spec limits to the data table and checked "show as graph reference line" box. The spec line showing in graph builder with no problem. However, when I try to use "Fit Curve" platform the reference line didn't show for some reason. Any help and suggestions will be highly appreciated.

Left one is graph builder and right one is Fit Curve.

Your Y axis on your fit curve graph only goes down to 450, and your LSL appears to be at 445 or so. If you change your minimum Y value to 430 or so, does your LSL show up?

Thank you for the help. I expanded my Y axis range and it still didn't show up.

It appears that prior to JMP 16, the Show Limits option is not honored by the Fit Curve platform. However, in JMP 16 it is

You will have to add the reference lines programmatically until you upgrade to JMP 16.

Names Default To Here( 1 );
dt = Open( "$sample_data/semiconductor capability.jmp" );
fc = Fit Curve(
	Y( :NPN1 ),
	X( :PNP1 ),
	SendToReport(
		Dispatch(
			{"Plot"},
			"5",
			ScaleBox,
			{Min( 103.62 ), Max( 128 ), Inc( 5 ), Minor Ticks( 1 )}
		)
	)
);

spec = :NPN1 << get property( "spec limits" );
fcr = fc << report;
fcr[axisbox( 1 )] << add ref line( spec["LSL"], solid, blue, "LSL" );
fcr[axisbox( 1 )] << add ref line( spec["Target"], solid, blue, "Target" );
fcr[axisbox( 1 )] << add ref line( spec["USL"], solid, blue, "USL" );

Thank you so much for your effort! I will try it on.
