How to add advanced Control Chart Builder Tests?

Question

https://community.jmp.com/t5/JMP-Blog/Custom-Tests-in-the-Control-Chart-Builder-in-JMP-10/ba-p/30115

The above article states that you can add custom tests to control charts, but it appears that this only works when the "Statistics" mode is set to "Average". I'm using "Moving Range on Means" which only offers the test for outside of Control Limits.

Is there a there a way of testing for, say, X points above or below Avg in this mode? I'm probably missing the statistical reason for this!

Thank you Jim. I'm starting to wrap my head around how JSL works!

To get the points from the Moving Averages chart, you can use the "Save Summaries" message and pass it to the Platform.  Below is a simple example of getting the points into a list:

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

theccb = dt << Control Chart Builder(
	invisible,
	Show Capability( 0 ),
	Variables( Y( :height ) ),
	Chart( Position( 1 ), Points( Statistic( "Moving Range" ) ), Limits( Sigma( "Moving Range" ) ) ),
	Chart( Position( 2 ), Limits( Sigma( "Moving Range" ) ) )
);
ccb = theccb << save summaries;

// The values from the Moving Range column(column 3) are numeric
// and would be returned as a matrix.  Therefore, to convert the
// results into a list, the As List() is added.
newList = As List( Column( ccb, 3 ) << get values );

close( ccb, nosave );
report( theccb ) << close window;

Is it possible to access the points created in the chart as a list? I'm familar with object orientated programming but I don't believe that JSL language would allow me to do something simiar to the following:

CCB = Control Chart Builder( ... some code to create CCB );
newList = CCB.Points();
