Factor combinations in Graph Builder

Tobias_Hofmann — Mon, 26 Jan 2026 11:06:51 GMT

Hello everybody,

so, I have the following relationship, looking at a timeseries (t,y), which is affected by additional variables A and B, as well as noise. My workflow is now: Design a DoE for variables A and B, measure, visualize, estimate/calculate effects of A and B. For this, we would like to plot and visually assess the data and the "disturbed" timeseries (t,y) depending on the factors.

This question is especially on the visualization of combined factors in GraphBuilder. See especially "plot2.png" produced by R and the corresponding "plot_jmp.png" produced by JMP. Please see how JMP keeps a space for non-existing groups, e.g. (FactorA,FactorB)=(1,10), (2,10), etc. whereas R reduces the plot automatically to the existing groups.

How would I do this the best way in JMP? I don't want to create a new column as a combination from factors A+B...

Example data given by the R-script.

Formula from my example:

a common issue in JMP:

A workaround:

In R, there is no nesting of the X Groups.
As you said, a column which combines the 2 levels can be used to generate this design.
you don't have to add it as a column to the data table, a dummy transform column (just inside the plot) is sufficient.
Best: use newline to reproduce the "hierarchy".

"empty white space" was identified as an issue and developers might work on it.
