JMP 14 does not have % of Factor option. However, you can still create the graph in JMP 14 by creating a new Column which represents the percent of the overlay group of the X group.
dt << New Column( "% of Factor",
formula(
Col Sum( :height, :age, :sex ) / Col Sum( :height, :age )
),
format( "Percent", 7, 1)
);
Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
dt << New Column( "% of Factor",
formula(
Col Sum( :height, :age, :sex ) / Col Sum( :height, :age )
),
format( "Percent", 7, 1)
);
dt = Graph Builder(
Variables(
X( :age ),
Y( :Name( "% of Factor" ) ),
Overlay( :sex )
),
Elements( Bar( X, Y, Legend( 9 ), Bar Style( "Stacked" ) ) )
);
