I know at least of one workaround for this as I have used in other case. You can add report to your new window and then collapse it
Names Default To Here(1);
dt = Open("$SAMPLE_DATA/Big Class.jmp");
gb = dt << Graph Builder(
Variables(X(:weight), Y(:height), Overlay(:sex)),
Elements(Points(X, Y, Legend(9)), Line Of Fit(X, Y, Legend(11)))
);
nw = New Window("not child",
Button Box("OK")
);
nw = New Window("is child",
vlb = V List Box(
Distribution(Nominal Distribution(Column(:sex)), Histograms Only)
),
Button Box("OK")
);
vlb << visibility("Collapse")
My topic where I asked how to force associated data for new window: What determines which data table is seen as "Associated Data" for New Window?
Wish list item: Allow setting associated data table(s) to a new window
