Greetings,

I'm using JMP 17, I tried to set control limit for IMR chart and X bar R chart.

Although I have set the control limits, when I run the script, the control limits do not change as I have set them.

dt is the data table.

below is the script for IMR chart:

```
dt = Open( "$SAMPLE_DATA/Time Series/Workers.jmp" );
Gra = dt << Control Chart Builder(
K Sigma( 2.5 ),
Variables( Subgroup( :DATE ), Y( :"electrical workers, thousands" ) ),
Chart(
Position( 1 ),
Warnings( Test 1( 1 ), Test 3( 1 ) ),
Set Control Limits( {LCL( 287.5 ), UCL( 312 ), Avg( 300 )} )
),
Chart(
Position( 2 ),
Warnings( Test Beyond Limits( 1 ) ),
Set Control Limits( {LCL( 0 ), UCL( 15 )} )
),
SendToReport(
Dispatch( {}, "Warnings[1]", OutlineBox, {Close( 0 )} ),
Dispatch( {"Warnings[1]"}, "Tests", OutlineBox, {Close( 0 )} ),
Dispatch( {}, "Warnings[2]", OutlineBox, {Close( 0 )} )
)
)
```

below is the script for XbarR chart:

```
dt = Open( "$SAMPLE_DATA/Quality Control/Line Length.jmp" );
Control Chart Builder(
K Sigma( 2.5 ),
Variables( Subgroup( :Run ), Y( :Length ) ),
Chart(
Position( 1 ),
Limits( Sigma( "Levey Jennings" ) ),
Warnings( Test 1( 1 ), Test 3( 1 ) ),
Set Control Limits( {LCL( 15.8 ), UCL( 16.2 ), Avg( 16 )} )
),
Chart(
Position( 2 ),
Limits( Sigma( "Levey Jennings" ) ),
Warnings( Test Beyond Limits( 1 ) ),
Set Control Limits( {LCL( 0 ), UCL( 0.16 )} )
),
SendToReport(
Dispatch( {}, "Warnings[1]", OutlineBox, {Close( 0 )} ),
Dispatch( {"Warnings[1]"}, "Tests", OutlineBox, {Close( 0 )} ),
Dispatch( {}, "Warnings[2]", OutlineBox, {Close( 0 )} )
)
)
```

How to set the control limit?

Thanks in advance
