Re: Bug in Control Charts??

[Mark4Flies@aol.com]

You can't supply variables for Control Chart arguments. This omission is a shortcoming in JSL.

Try this work around:

mean = 1.7;
lcl = 1.3;
ucl = 2.1;

Eval(
     Substitute(
          Expr(
               Control Chart(
                    Sample Label( Name( "Emul/Order" ) ),
                    K Sigma( 3 ),
                    Chart Col(
                         :FTC_B,
                         Individual Measurements(
                              Avg( aaa ),
                              LCL( lll ),
                              UCL( uuu )
                         )
                    )
               )
          ),
          Expr( aaa ),
          mean,
          Expr( lll ),
          lcl,
          Expr( uuu ),
          ucl
     )
);
