Adding mean line by script

Jemster — Fri, 09 Jun 2023 17:04:49 GMT

I can build a graph and add a horizontal mean line. When I try to extract the script it doesn't reproduce any line.

I have attached the script below

Graph Builder(
	Size( 1964, 1192 ),
	Variables( X( Column ), Y( Column ), Group X( Column_a ) ),
	Elements( Bar( X, Y, Legend( 11 ) ), Line( Y, Legend( 12 ) ) ),
	Local Data Filter(
		Add Filter( columns( Column_a ), Where( Column >= 0 & Column_a <= 3.2 ) )
	),
	SendToReport(
		Dispatch( {"Line"}, "", OutlineBox, {Close( 0 )} ),
		Dispatch(
			{},
			"400",
			ScaleBox,
			{Legend Model(
				11,
				Properties( 0, {Fill Color( 0 )}, Item ID( "Column", 1 ) )
			)}
		)
	)
);

You'll need to provide more information -- How are you adding the line? Can you provide a script that uses an example data table so that we can test?

Here is an example of adding a Line to an existing Graph Builder plot

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
gb = Graph Builder(
	Variables( X( :height ), Y( :weight ) ),
	Elements( Points( X, Y ), Smoother( X, Y ) )
);
gbb = Report( gb )[Graph Builder Box( 1 )];
gbb << Add Element( 1, 1, {Type( "Line" ), X, Y} );

The documentation for the messages that can be sent to Graph Builder are found in the Scripting Index.

Thank you, this works to add a line but I was wondering how I can change it so that the line is a horizontal line displaying the mean Y variable

Go to the Scripting Index and search on

I overlayed the two graphs onto one plot by adding the script for the line graph I wanted into the elements section of the script
