Is Fit Group supposed to actually force by graphs inside it to respect by columns? It seems like the graphs are just being duplicated with a header that says Fit Group age=12, sex=M.
names default to here(1);
dt = open("$SAMPLE_DATA\Big Class.jmp");
fg = dt << Fit Group(
dt << OneWay( Y( :weight, :height ), X( :name ) ),
<<{Arrange in Rows(2)},
By(:age, :Sex)
); //I like the way this looks but it doesn't seem to actually respect the By in the graphs
//this one respects the by but puts the groupings in each graph which is pretty ugly
//and doesn't arrange in rows
g1 = dt << Oneway( Y( :weight, :height ), X( :name ), By(:age, :Sex) )
