Graph Builder, how to change the color of an element, and information about SendToReport syntax

newbie_alex

Hello,

 

I create a graph with dynamic content (number of variables is determined at run time).

 

I would like to change to change several things after setting up the graph builder, e.g. assign a new color. The reason for doing it afterwards is because, I do not know the changes before executing other parts of my script that I cannot run earlier.

 

I have simplified my basic problem to this example:

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );

gb = Graph Builder(
	Automatic Recalc( 0 ),
	Variables( X( :age ), Y( :height ) ),
	Elements( Points( X, Y ), Smoother( X, Y ) )
);

// do some other stuff incl. addition or removal of variables to gb

// how do I *MODIFY* the color of Points, Smoother here or add a Line Plot?

I know the position of the variables in the graph if that helps (1,1 in the example above).

 

Cheers,

Alex

Just do it interactively, and then inspect the code that JMP generates for you. Adapting your example:

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );

gb = Graph Builder(
	Automatic Recalc( 0 ),
	Variables( X( :age ), Y( :height ) ),
	Elements( Points( X, Y, Legend( 1 ) ), Smoother( X, Y, Legend( 2 ) ) )
);

// Add 'weight'
Wait(2);
gbb = Report( gb )[Graph Builder Box( 1 )];
upper_graph_inner_pos = 2;
gbb << Add Variable({Column( "weight" ), Role( "Y" ), Position( 1 ), Inner Position( upper_graph_inner_pos )});

// Change the colour of the points and smoother for 'weight' to green
Wait(2);
gb << SendToReport( Dispatch({}, "400", ScaleBox, {Legend Model( 2, Properties( 1, {Line Color( 4 )} ) )} ) );

Regarding the less important question, you can look in 'Help > Books > Scripting Guide' which often gives some pointers.
