Variability Plot Grouping

[#1]

Hi, 

I have a bunch of variability plots to show on a single window with same columns grouping. How will I just define the x_grouping at the very top, so that I can change the grouping in only one place. For example, I want to define grouping by :xA, :xB, and ;xC outside the function "variability chart ( )", so that I can change grouping columns in one place only. Thanks. 

Names Default To Here( 1 );

dt = Current Data Table( );

/*

A general grouping variable for X grouping.

*/


New Window(
	"Variability",
	V List Box(
		Variability Chart(
			Y( :Y1 ),
			X( :xA, :xB, :xC ),
		),
		Variability Chart(
			Y( :Y1 ),
			X( :xA, :xB, :xC ),
			Connect Cell Means( 1 )
		)
	)
);

You can create multiple variability plots with one Variability Plot() platform statement 

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


New Window(
	"Variability",
	V List Box(
		vc = dt << Variability Chart(
		Y( :LogHist0, :LogHist1, :LogHist3, :LogHist5 ),
		X( :drug, :dep1 ),
		Connect Cell Means( 1 ),
		Std Dev Chart( 0 )
	)
  ) //end VListBox
);

show(vc);
//vc = {Variability Chart[], Variability Chart[], Variability Chart[], Variability Chart[]};

//you can reference and change the the plots, see below

report(vc[1])[FrameBox(1)] << select;

Can you explain the purpose of these two statements a bit more?

Show( vc );
//vc = {Variability Chart[], Variability Chart[], Variability Chart[], Variability Chart[]};
Report( vc[1] )[FrameBox( 1 )] << select;

@RA ,

When scripting, it is useful to create variable references to the objects, in your case the 4 variability charts.  I do not know your JSL experience, so those statements are showing you how to create a variable reference to the varaibility charts.  

• vc = dt << Variability Chart()  sets up a reference to a list of the varaibiity charts created by  this statement
• you can referencs them in a for loop   For( i=1, i<=nitems(vc), i++, vc[i] <<   ...   or report( vc[i]  ) << ...
• some options you can change all  vc << Std Dev(1)

//change var chart
report(vc[1])[FrameBox(1)] << {Background Color( 32)} ;

//change all var charts
vc << Connect Cell Means(0);
wait(2);
vc << Connect Cell Means(1);

My goal was inform you of this capability just in case you were not aware, that is, I was anticipating a next question.  Sorry if it was unclear.

I am new to jsl. This referencing tip is highly appreciated.

Is there to way to define the limits and axis range independently for each variability plot by this method?

For example if I wanted to add a horizontal line at -1 on one plot and 0 on the next one, can we do that ?
