Use the in column command to save the limits to the column. Here is an example.
dt = Open("$SAMPLE_DATA/Quality Control/Diameter.jmp");
obj = dt<<Control Chart Builder(
Variables( "Subgroup"(:DAY), "Y"(:DIAMETER) ),
Chart(
Position( 1 ),
Points( Statistic( "Average" ) ),
Limits( Sigma( "Range" ) ),
Connecting Line( 1 )
),
Chart(
Position( 2 ),
Points( Statistic( "Range" ) ),
Limits( Sigma( "Range" ) ),
Connecting Line( 1 )
)
);
obj << in Column; // *Save Limits in Column*
