Control chart builder JMP 19 - How to group together X axis values

SophieCuvillier — Mon, 23 Feb 2026 10:49:41 GMT

Hello,

We migrated from JMP18 to JMP19 and noticed a change in behavior in the control chart builder. In the example below, I have a double X-axis with Sample first and then Product. I liked the fact that in JMP18 the values were grouped together, which made it more visually readable. I know that in this example the order is different because category A comes at the end, but let's assume that this was not the case; it doesn't change the visual.

Since JMP19, I have a repetition of my product sub-axis: A, A, A, A, B, B, B... which is not great for me visually. Is there a way to merge them, as was possible in JMP 18?

Attached the control charts picture in JMP18 and 19

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Quality Control/Coating.jmp" );

dt << Control Chart Builder(
	Variables(
		Subgroup( :Product ),
		Subgroup( :Sample, Position( 1 ) ),
		Y( :Weight )
	),
	Show Control Panel( 0 )
);

Does enabling Sort By Subgroup (from red triangle menu) do what you are looking for?
