sorry Jim, I think I am confused with your answer,
I added
Eval(
Substitute(
Expr(
:REM OX << Set Property(
"Control Limits",
{XBar( Ave( __avg__ ), LCL( __LCL__ ), UCL( __UCL__ ) ),
Show Control Limits( 1 )}
)
),
Expr( __avg__ ), :Center Line[1],
Expr( __LCL__ ), :Lower Limit[1],
Expr( __UCL__ ), :Upper Limit[1],
),
);
to my script to upload the limits.
It does not show any thing on the charts. It is working for Spec limits.
I could not understand your comment about Show Control limits()
