Greetings,
I'm using JMP 17, I tried to set control limit for chart A (x-bar) and chart B (R)
edt is the data table.
below is my script:

graph = edt << Control Chart Builder(
Size( 1123, 586 ),
Show Alarm Report( 1 ),
Show Control Panel( 0 ),
K Sigma( 2.5 ),
Variables( Subgroup( :CaptureDateTime ), Y( :CaptureValue ) ),
Chart(
Position( 1 ),
Limits,
Set Control Limits( {LCL( 49.5 ), UCL( 50.5 ), Avg( 50 )} ),
Warnings( Test 1( 1 ), Test 3( 1 ) )

),
Chart(
Position( 2 ),
Set Control Limits( {LCL( 0 ), UCL( 0.8 )} ),
Warnings( Test Beyond Limits( 1 ) )
))

but once I run the script, it does not set the control limits. Anyone knows how to set control limit in script?
thank in advanced

The problem could be that you are trying to set the limits characteristics without specifying them.

Try to set them

...

Position( 1 ),
Limits (Sigma ("......" ) ),
Set Control Limits( {LCL( 49.5 ), UCL( 50.5 ), Avg( 50 )} ),

...

or try to delete the line Limits, .

I hope this helps.
