With nominal values on the x axis and X group activated, the axes of the sub-plots share a common list of values.

All plots show all values.

In the example below, X group says that girls are in the left plot and boys are in the right plot.

But due to axis sharing between both subplots, boys and girls show up on the axes of both plots.
This is counter-intuitive and consumes unnecessary space.

With some steps the underlying data table can be changed to generate a plot with girls just on the left and boys on the right:

Would be great to have a right click option to directly "disentangle" the axis settings such that each axis gets (just) its own values.

similar topics:

- same effect for y axis values and Y group

- different axis scaling for continuous values in different sub-plots.

example: Plot with male and female students.

Unfortunately, the plot on the left (F!) lists also all the  male students - and the plot on the right (M!) all the female students !??!

@Jeff_Perkinson just mentioned this wish on Discovery Summit 2026 and explained that the desired improvements collide with other features in JMP.

Can we think of a light version of this wish?

Let's take big class - with 18 female and 22 male students.
With the original idea of the wish, the plot will be asymmetric -  with the plot region for the male students slightly larger than for the female students.


But how about a light version -  a plot with same size for male and female students?
With 22 slots available - and just 18 female slots filled?

Going further along this line, we would need something like col score() on the X axis, but not with number as tick labels.
We have to replace them with the names of actual students - separate labels for females and males!

The closest I can get is this:

To pass the finish line, I guess we need some support from @XanGregg and his team ...

Names Default to Here(1);
dt = Open( "$SAMPLE_DATA/Big Class Families.jmp" );
Graph Builder(
	Transform Column(

	Show Legend( 0 ),
	Graph Spacing( 4 ),
	Variables(

				Tick Mark Style( "Long Divider" ),
				Tick Mark( Label( "1" ), Label( "1st student's name" ) ),
