Setting using JSL so that the control chart does not display batches for which there are missing data for a given parameter.

Giardini

As the topic.

Normally in JSL we indicate batches (represented by a given column) for which we present points on the control chart as follows:

Local Data Filter(
		Close Outline( 1 ),
		Add Filter(
			columns( :Batch ),
			Where(
				:Batch == {"01/10/2022", "01/11/2022", "01/12/2022", "01/13/2022"}
			),
			Display( :Batch, N Items( 15 ), Find( Set Text( "" ) ) )
		)
	),

However, how can we request that all batches be taken into account, except those for which we have N/A (empty field in the data table) for a given parameter?

One way would be to use an associative array to get all the unique values, then keep just the non-missing values. Then, you could pass this as a list to the local data filter. Example below:

Names Default To Here (1);
//open file and delete a few data points
dt = open ("$SAMPLE_DATA/Abrasion.jmp");

for each ({i}, 6::9,
	:Date[i] = .
);

//get non-missing 
lstdates = matrix (Associative Array (:Date) << Get Keys);
lstdates = as list(lstdates[loc(!Is Missing(lstdates))]);

//launch cc
cc = Control Chart Builder( Variables( Y( :Abrasion ) ), Show Control Panel( 0 ), );

//launch data filter
ldf = cc << Local Data Filter(
	Add Filter(
		columns( :Date ),
		Where( :Date == lstdates ),
		Display( :Date, N Items( 5 ) )
	)
);

I am a big fan of using transform columns right inside platforms. Here is how I created the control chart part of the script below:

Create the control chart using all data
In the control panel, right click on Date and choose Formula
Add Is Missing and Not functions so the formula is true when the column Date is not missing and close the dialog
Right click on the new column and rename it to be 'HasDate'
Right click on blue triangle next to the new column and change it to a Nominal data type
Add a local data filter, the transformed column will automatically show up in the list of available columns

Here is what you should get:

And here is the script to re-create it:

Names Default To Here (1);

dt = open ("$SAMPLE_DATA/Abrasion.jmp");

dt << Control Chart Builder(
	Transform Column( "HasDate", Nominal, Formula( !Is Missing( :Date ) ) ),
	Variables( Y( :Abrasion ) ),
	Show Control Panel( 0 ),
	Local Data Filter( Add Filter( columns( :HasDate ), Where( :HasDate == 1 ) ) )
);

If after you decide that is a helpful column creating a visual or doing an analysis , you can right click on it and add it to the data table.

Very nice, @ih !

Giardini

Thank You. I think your answer is close to what I want, and only a slight modification of the code would allow me to achieve the desired result. Unfortunately, I am at the beginning of my journey with the JMP SL, I would be grateful if you could help me obtain a code that would fully implement what I want to achieve.Therefore, I will try to explain my problem better.

I need to say, that I use a loop to want control charts to be executed for different parameters from the data table. I'm having trouble with how, using your previous tip, I can change the code to take the i-th column as the one to filter on. I tried :Column(i), but I don't think that's the way...

I'm sharing a piece of code from my attempt to explain what I mean.

For( i = 2, i <= 5, i++,
	dt << Control Chart Builder(
		lstdates = Matrix( Associative Array( :Column( i ) ) << Get Keys );
		lstdates = As List( lstdates[Loc( !Is Missing( lstdates ) )] );
		Show Two Shewhart Charts( 0 );,
		Sort by Row Order( 1 ),
		Include Missing Categories( 0 ),
		Show Excluded Region( 0 ), //sprawdź które to które
		Show Limit Summaries( 0 ),
		Variables( Subgroup( :Batch ), Y( :Column( i ) ) ),
		Chart(
			Points( Statistic( "Individual" ) ),
			Limits( Sigma( "Levey Jennings" ) ),
			Warnings( Test 1( 1 ), Test 2( 1 ), Test 3( 1 ), Test 4( 1 ) )
		),
		ldf = cc << Local Data Filter(
			Add Filter( columns( :Column( i ) ), Where( :Column( i ) == lstdates ), Display( :Column( i ), N Items( 5 ) ) )
		),
		SendToReport(
			Dispatch( {}, "graph display 1 title", TextEditBox, {Set Text( "Levey Jennings chart of " || Nazwy[i] )} ),
			Dispatch( {}, "Subgroup display 1 title", TextEditBox, {Set Text( "Batch numer" )} )
			)
		);
	)
);

Don't you know maybe what should I write instead :Date, if I' m going to use loop "for" for every continous parameter in my data table?

Jed_Campbell

This sample should show you how to get all the continuous columns into a list, then loop through those columns. Incidentally, if you are looking at multiple columns, have you considered either the Model Driven Multivariate Control Chart or the Process Screening Platform? Both of those excel at streamlining control charts for multiple outputs.

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

//get all numeric continuous colums, return list as strings
lstcols = dt << Get Column Names( Numeric, Continuous, String );

//run an analysis for each column in the list
For Each( {i}, lstcols,
	dt << Graph Builder(
		Show Control Panel( 0 ),
		Variables( X( :age ), Y( Column( i ) ) ), //Use each column
		Elements( Points( X, Y, Legend( 3 ) ) )
	)
);

I think what I don't understand is why referring to a given column by its name (for example ':name') would work in my script but by 'column(i)' it doesn't (I know that in the code above I made a mistake by writing :column(i ), instead of column(i), but correcting it didn't change anything...)
