What determines the order of the platforms in a group-by analysis

[#1]

I expected the value order of a column to define which value is shown first in analysis platforms when grouping by that column, but this does not seem to be the case (sex=F is always shown first in big class).

My question is twofold:

1. can I affect which is shown first?

2. If not, how do I know which comes first? It does not appear to be alphabetical

dt=Open("$SAMPLE_DATA\big class.jmp");
Distribution( Continuous Distribution( Column( :height ) ), By( :sex ) )

[#2]

How come it doesn't seem to be alphabetical? Quickly tested by using with Big Class and using :name as by column and to me it seems like it is in alphabetical order

Names Default To Here(1);

dt = Open("$SAMPLE_DATA\Big Class.jmp");

dist = dt << Distribution(
	Continuous Distribution(Column(:height)), By(:name),
	Histograms Only
);


show((dist << Xpath("//OutlineBox[contains(text(), 'Distributions name=')]")) << get title);

Next question would be:
how chan I change ...

I could bet that yesterday it didn't work

[#6]

But today it does? This was on JMP 17 but I think this has been working for a while.

Yes, works with jmp 16 and 17.
hm ..."yesterday". I don't know ...
