I have a heat map that needs some nested groups (in order to properly show values inside the heat map) squares. My issue is that a lot of the rows are entirely missing because it forces every group to exist. Is there a way to only show valid groups? For example:
Names Default to here(1);
dt = open("$SAMPLE_DATA\Big Class.jmp");
rows = dt << Get Rows Where(:age == 14 & :sex == "M");
dt << delete rows(rows);
dt << Graph Builder(
Variables( Group Y( :sex ), Group Y( :age ), Color( :height ) ),
Elements( Heatmap( Legend( 4 ) ), Caption Box( Legend( 5 ) ) )
);
Gives.

I don't want to see the 14 year old Male category.
Or, if you know a better way to show the means for a column inside the square, I'd take that too.
