Heatmap Using Maximum instead of Mean

[#1]

Hello

Is it possible to create a heatmap using the maximum value at each (x, y) rather than the average?

Thanks!

You can do this, but you have to preprocess the statistics.  See the simple script below for an example

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA\big class.jmp" );
dtmax = dt << Summary( Group( :sex, :age ), Max( :height ), Freq( "None" ), Weight( "None" ) );
New Window( "graphs",
	H List Box(
		dt << Graph Builder(
			Size( 570, 520 ),
			Variables( X( :SEX ), Y( :Age ), Color( :height ) ),
			Elements( Heatmap( X, Y, Legend( 4 ) ) )
		),
		dtmax << Graph Builder(
			Size( 570, 520 ),
			Variables( X( :SEX ), Y( :Age ), Color( :name( "max(height)" ) ) ),
			Elements( Heatmap( X, Y, Legend( 4 ) ) )
		)
	)
);
