JSL Chart Builder Control Limit for multiple measurement set name

FrankBot0211

Hi, I want to draw a control chart to show violate test point with arround 10 measurement sets base on 10 sets of online control limit in another table. Can anyone tell me how to load the multiple control limit follow by measurement set name?

Below is my draft scriptting

 

Names Default To Here( 1 );
dt = Open(
"./MRK.jmp"
);
obj =
Control Chart(
Sample Size( :Sample ),
KSigma( 3 ),
Chart Col( :Weight ),
Chart Type( XBar )
By:(:Mesurement_Set_Name)
);
obj << Test 1( 1 );

dt2 = obj << SaveSummaries;
// Rule violations occur in dt2 in the column "Test Failures" as comma delimited text ("" if no violations)
dt2 << SelectWhere(:Test Failures != "");

Here is a way that should work.  It involves using a saved limits table that contains phases, and creating a new column in your data table that has the same value as your Measurement_Set_Name.

In your raw data table, add in a new column by the name of 

     measurement_set_name_phase

The reason for this, is that you need to have both a By value set and a Phase value set, and JMP will not allow the same variable to be used by both By and Phase.

Next create a limits table fashioned like the following:

Tonja from JMP has a blog with an entry about this

https://community.jmp.com/t5/JMPer-Cable/4-ways-to-use-fixed-baseline-historical-control-limits-in/b...

Now go into your XBar Chart and set it up, specifying measurment_set_name as the By and measurement_set_name_phase and the Phase variable, 

Then click on the "Read Limits" button.  It will open a folder for you to specify which jmp file to read in.  So above, when you are finished creating the limits table, you need to save it to a folder.

Now you can run your XBar chart.

I did have an issue with setting a fixed value for sample size, but your data may not have an issue.  However, I did get it to work by specifying a Sample Label variable
