Hiding Legend Items in Graph Builder using JSL

I am having an annoying issue with the Graph Builder in JSL.  In order to show both the points and a smoother on a scatter plot I am changing the trasnparency of the points.  I can make this work well enough but when I manipulate the plot later in JSL the points are being added back to the legend by default instead of staying hidden I assume because JMP thinks they are no longer redundant.  I know manually in the graph builder you can uncheck items that you don't want to display but is there a way to do this in JSL?

Re: Hiding Legend Items in Graph Builder using JSL

I found an alternate solution that in my view is cleaner then Jim's brute force method.

 

Instead I am defining two lists at the beginning of my function:

 

	p = {};
	l = {};
	summarize(unique_values=by(OverlayCol));
	NSplits = N Items (unique_values);
	
	For(i=0, i < NSplits, i+=1,
		p = Insert(p, -1);
		l = Insert(l, i);
	);
	pl = Insert(p, l);

to create the two lists needed for the points and lines (in my case) legend items then passing those lists as matrices that into the graph builder dispatch as follows:

 

			Dispatch(
				{},
				"400",
				LegendBox,
				{Legend Position( {3, Matrix(p), 9, Matrix(l)} ), 
				Position( Matrix(pl))}
			)

Full version of the updated function:

 

RadPlotCreator1XGroupTest = Function({dt, XCol, YCol, OverlayCol, GroupXCol}, {Default Local},
	
	p = {};
	l = {};
	summarize(unique_values=by(OverlayCol));
	NSplits = N Items (unique_values);
	
	For(i=0, i < NSplits, i+=1,
		p = Insert(p, -1);
		l = Insert(l, i);
	);
	pl = Insert(p, l);
	
	
	gb =  dt << Graph Builder(
		Size( 849, 622 ),
		Fit to Window( "Off" ),
		Show Control Panel(0),
		Grid Color( "Black" ),
		Variables(
			X( XCol ),
			Y( YCol ),
			Group X( GroupXCol ),
			Overlay( OverlayCol )
		),
		Elements(Points(X, Y, Legend(3)), Smoother( X, Y, Legend( 9 ) )),
		SendToReport(
			Dispatch(
				{},
				"",
				ScaleBox,
				{}
			),
			Dispatch(
				{},
				"",
				ScaleBox,
				{}
			),
			Dispatch(
				{},
				"400",
				LegendBox,
				{Legend Position( {3, Matrix(p), 9, Matrix(l)} ), 
				Position( Matrix(pl))}
			)
		)
	);


	sb = report(gb)[ScaleBox(5)];
	For(i=0, i < NSplits, i+=1,
		sb << Legend Model(3, Properties(i, {Transparency(0.2)}));
	);

	frame_list = gb << xpath("//FrameBox");
	num_frames = N Items (frame_list);


	For(i=1, i <= num_frames, i+=1,
			Report(gb)[Framebox(i)] << Background Color(White);
			Report(gb)[Framebox(i)] << Grid Line Order( Back );
			Report(gb)[Framebox(i)] << Reference Line Order( Back );
			Report(gb)[Framebox(i)] << Frame Size(250, 250);
			Report(gb)[Framebox(i)] << X Axis(0, 150, Inc(20), Minor Ticks(1),
				Add Ref Line( 70, Solid, "Black", "", 2 ), 
				Add Ref Line( 120, Solid, "Black", "", 2 ), 
				Add Ref Line( 135, Solid, "Black", "", 2 ), Show Major Grid( 1 ));
			Report(gb)[Framebox(i)] << Y Axis(Minor Ticks(1));
	);

	gbp = Report( gb );
	img = gbp << getpicture();
	
	return(img);
	
);

Re: Hiding Legend Items in Graph Builder using JSL

I guess there is no JSL solution for this.  If that is the case there very much should be.

Re: Hiding Legend Items in Graph Builder using JSL

Hi everyone,

I am currently facing the same problem: hiding a part of the Graph Builder legend using JSL.

I think the options "Legend" or "Legend position" could help but I have difficulties to fully understand how it works, in particular if we do not know the number of groups.

 

For instance I want to create this kind of graph using the Big Class table, and I do not want to display the point items in the legend:

Graph Builder.png

The corresponding script is:

Graph Builder(
	Size( 528, 450 ),
	Show Control Panel( 0 ),
	Variables( X( :age ), Y( :height ), Color( :age ) ),
	Elements( Box Plot( X, Y, Legend( 4 ) ), Points( X, Y, Legend( 5 ) ) ),
	SendToReport(
		Dispatch(
			{},
			"400",
			LegendBox,
			{Legend Position(
				{4, [0, 1, 2, 3, 4, 5, 6, -3], 5, [-1, -1, -1, -1, -1, -1]}
			), Position( {0, 1, 2, 3, 4, 5, 6, -3, -1, -1, -1, -1, -1, -1} )}
		)
	)
)

Is there a way to generalize the process without knowing the number of levels for the age variable?

 

Any input would be appreciated :) Thanks

Re: Hiding Legend Items in Graph Builder using JSL

You can use the Show Legend element to control the showing or hiding of the Legend.  Here is the entry from the Scripting Index showing it

     Help==>Scripting Index

showlegend.PNG

You can also delete the entire Legend component by deleting it using the Display Tree capabilites in JMP

gb = Graph Builder(
	Size( 528, 450 ),
	Show Control Panel( 0 ),
	Variables( X( :age ), Y( :height ), Color( :age ) ),
	Elements( Box Plot( X, Y))
);
report(gb)[LegendBox(1)]<<delete;

Re: Hiding Legend Items in Graph Builder using JSL

Hi @txnelson,

 

Thanks for your reply.

However I do not want to completely hide or delete the legend but just a part of it.

By default I have the following graph:

Graph Builder1.png

 

And I would like to hide only the point items in the legend to get that one:

Graph Builder.png

 

Apparently "-1" in the legend position option means "hide this item" but I do not see how to easily use this option without prior information about the graph.

I hope it is clearer.

Re: Hiding Legend Items in Graph Builder using JSL

What version of JMP are you using, and on which operating system.  Using the JSL you provided, I can not get results like you are specifying.  For JMP 15 I get

pic15.PNG

In JMP 13 and JMP 14 I get:

pic1314.PNG

In JMP 11 and JMP 12, I get:

pic1112.PNG

But I can not get the graph you present with the different markers, and both the points and the rectangular marking in the legend.

Re: Hiding Legend Items in Graph Builder using JSL

I personally get the dual legends in both JMP 12 and JMP 14.  I didn't post my code earlier but below is the function I use to make the plots where I have the issue.  In my case I believe what is happening is that as soon as I use the bit of code to set the transparency of the points that JMP no longer thinks the points legend item is redundant and displays the result.

 

RadPlotCreator1X1YGroup = Function({dt, XCol, YCol, OverlayCol, GroupXCol, GroupYCol}, {Default Local},
	
	gb =  dt << Graph Builder(
		Size( 849, 622 ),
		Fit to Window( "Off" ),
		Show Control Panel(0),
		Grid Color( "Black" ),
		Variables(
			X( XCol ),
			Y( YCol ),
			Group X( GroupXCol ),
			Group Y( GroupYCol ),
			Overlay( OverlayCol )
		),
		Elements(Points(X, Y, Legend(3)), Smoother( X, Y, Legend( 9 ) )),
		SendToReport(
			Dispatch(
				{},
				"",
				ScaleBox,
				{}
			),
			Dispatch(
				{},
				"",
				ScaleBox,
				{}
			)
		)
	);

	summarize(unique_values=by(OverlayCol));
	NSplits = N Items (unique_values);
	sb = report(gb)[ScaleBox(5)];
	For(i=0, i < NSplits, i+=1,
		sb << Legend Model(3, Properties(i, {Transparency(0.2)}));
	);

	frame_list = gb << xpath("//FrameBox");
	num_frames = N Items (frame_list);


	For(i=1, i <= num_frames, i+=1,
			Report(gb)[Framebox(i)] << Background Color(White);
			Report(gb)[Framebox(i)] << Grid Line Order( Back );
			Report(gb)[Framebox(i)] << Reference Line Order( Back );
			Report(gb)[Framebox(i)] << Frame Size(250, 250);
			Report(gb)[Framebox(i)] << X Axis(0, 150, Inc(20), Minor Ticks(1),
				Add Ref Line( 70, Solid, "Black", "", 2 ), 
				Add Ref Line( 120, Solid, "Black", "", 2 ), 
				Add Ref Line( 135, Solid, "Black", "", 2 ), Show Major Grid( 1 ));
			Report(gb)[Framebox(i)] << Y Axis(Minor Ticks(1));
	);

	gbp = Report( gb );
	img = gbp << getpicture();
	
	return(img);

Re: Hiding Legend Items in Graph Builder using JSL

Ooops wrong copy / paste sorry for the confusion!

Let's redo it (using JMP15)!

First I have the following graph:

Graph Builder2.png

And the corresponding script is:

Graph Builder(
	Variables( X( :age ), Y( :height ), Color( :age ) ),
	Elements( Points( X, Y, Legend( 6 ) ), Box Plot( X, Y, Legend( 7 ) ) )
)

Manually I modify the legend and deselect items associated with the points:

Image1.png

I get this graph:

Graph Builder3.png

And the updated script is:

Graph Builder(
	Variables( X( :age ), Y( :height ), Color( :age ) ),
	Elements( Points( X, Y, Legend( 6 ) ), Box Plot( X, Y, Legend( 7 ) ) ),
	SendToReport(
		Dispatch(
			{},
			"400",
			LegendBox,
			{Legend Position(
				{6, [-1, -1, -1, -1, -1, -1], 7, [0, 1, 2, 3, 4, 5, 6, -3]}
			), Position( {-1, -1, -1, -1, -1, -1, 0, 1, 2, 3, 4, 5, 6, -3} )}
		)
	)
)

Is there an easy way to manage this second step with JSL?

Re: Hiding Legend Items in Graph Builder using JSL

Here is the brute force way that I use to solve these kind of issues.  I simply build the JSL code required and then run the JSL I created. Please note that in the Big Class data table I used, I added an additional Age Group, of 18.

Names Default To Here( 1 );
dt = Current Data Table();

// Find the number of Age groups
Summarize( dt, ageGroups = by( :age ) );

// Build the JSL
theExpr =
"Graph Builder(
	Show Control Panel( 0 ),
	Variables( X( :age ), Y( :height ), Color( :age ) ),
	Elements( Points( X, Y, Legend( 6 ) ), Box Plot( X, Y, Legend( 7 ) ) ),
	SendToReport(
		Dispatch(
			{},
			\!"400\!",
			LegendBox,
			{Legend Position(
				{6, [ -1";

For( i = 2, i <= N Items( ageGroups ), i++,
	theExpr = theExpr || ", -1"
);

theExpr = theExpr || "], 7, [0";

For( i = 1, i <= N Items( ageGroups ), i++,
	theExpr = theExpr || ", " || Char( i )
);

theExpr = theExpr || ", -3]}
	), Position( {-1";
	
For( i = 2, i <= N Items( ageGroups ), i++,
	theExpr = theExpr || ", -1"
);

For( i = 0, i <= N Items( ageGroups ), i++,
	theExpr = theExpr || ", " || Char( i )
);

theExpr = theExpr || ", -3]} ) } )));";

// Execute the JSL string
eval(parse(theExpr));
