JSL add a title to Control charts

[#1]

Hello, here a script to plot control charts (all the control limits are set by the user and this part of the code is not shown here). How can I modify the script to modify the title of the control chart?

Thank you very much!

		dt << Control Chart Builder(
			Size( 719, 464 ),
			Show Two Shewhart Charts( 0 ),
			Show Control Panel( 0 ),
			Show Capability( 0 ),
			Show Limit Summaries( 0 ),
			Variables( Subgroup( :column( Lot ) ), Y( :column( CQA ) ) ),
			Chart(
				Points( Statistic( "Individual" ) ),
				Add Spec Limits( {LSL( LSL_def ), USL( USL_def )} ),
				Set Control Limits( {LCL( LCL_def ), UCL( UCL_def ), Avg( Avg )} ),
				Warnings( Test 1( 1 ), Test 2( 1 ), Test 3( 1 ) )
			),
			SendToReport(
			
				Dispatch(
					{},
					Variable,
					ScaleBox,
					{Min( Min( LCL_def, LSL_def ) - 1 ), Max( Max( UCL_def, USL_def ) + 1 ), Inc( 1 ), Minor Ticks( 0 ),
					Add Ref Line( LSL_def, "Solid", "Blue", "LSL=" || Char( LSL_def ), 2 ), 
					Add Ref Line(
						USL_def,
						"Solid",
						"Blue",
						"USL=" || Char( USL_def ),
						2
					), 
					
					Add Ref Line( LCL_def, "Solid", "Red", "-" || Sigma || "σ=" || Char( LCL_val ), 1 ), Add Ref Line(
						UCL_def,
						"Solid",
						"Red",
						"+" || Sigma || "σ=" || Char( UCL_val ),
						1
					), 
					
					Add Ref Line( Avg, "", "Green", "µ=" || Char( Avg ), 1 ), Label Row( Set Font Style( "Bold" ) )}
				),
				Dispatch(
					{},
					"Control Chart Builder",
					FrameBox,
					{Add Graphics Script( 2, Description( "" ), Text( {10, 100}, "" ) ), Add Graphics Script(
						3,
						Description( "" ),
						Pen Color( "black" );
						V Line( Split - 0.5 );
					), Grid Line Order( 1 ), Reference Line Order( 4 ), DispatchSeg(
						TopSeg( 2 ),
						{Set Script(
							Pen Color( "black" );
							V Line( Split - 0.5 );
						)}
					)}
				)
			)
		)

You can do this by simply referencing the text box that holds the title, and then update it.

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/big class.jmp" );
dt << Control Chart Builder( Variables( Y( :height ) ), Show Control Panel( 0 ) );
Current Report()[Text Box( 1 )] << set text( "new title" )
;

Thank you very much !

I have a last question. I want to change the title of the Control Chart according to the levels of my "Strength" variable.

I used your code and modify it:

summarize(dt,SubSet_Strength=by(:Strength));

Current Report()[Text Box( 1 )] << set text(Char( Variable)||" - "||Char( SubSet_Strength ) );

And I got the following result:

How can I have the levels of my Strength variable with the commas, but without parenthesis and quotation marks?

Thank you!

Your Subset_Strength is a JMP List, not a character string.  You can use Concat Items() to take the elements of the list, an move them to a Character String, which can then be used as you want it.

Summarize( dt, SubSet_Strength = by( :Strength ) );

Current Report()[Text Box( 1 )] << set text( Char( Variable ) || " - " || Concat Items( Subset_Strength, ", " ) );

Perfect! Thank you so much!
