When I have several columns that have user defined control limits (as a Column Property), and I runProcess Screening, the resulting table doesn't show the limits. All the tests and related alarms are nicely displayed, but it would be also nice to see the limits. Is there a way to show them?

Solution

You can always do this kind of thing:

```
NamesDefaultToHere(1);
// Make a table
dt = New Table( "Test",
New Column( "Column 1",
Numeric,
"Continuous",
Formula( Random Normal() ),
Set Property(
"Control Limits",
{Individual Measurement( Avg( 1 ), LCL( 0 ), UCL( 2 ) )}
)
),
New Column( "Column 2",
Numeric,
"Continuous",
Formula( Random Normal( 3 ) ),
Set Property( "Control Limits", {XBar( Avg( 3 ), LCL( 0 ), UCL( 6 ) )} )
)
);
dt << addRows(1000);
// Do the Process Screening
ps = dt << Process Screening( Y( :Column 1, :Column 2 ), Control Chart Type( "Indiv and MR" ) );
// Add the limits
tb = Report(ps)[TableBox(1)];
cols = Report(ps)[StringColBox(1)] << get;
avg_ = J(NItems(cols), 1, .);
lcl_ = J(NItems(cols), 1, .);
ucl_ = J(NItems(cols), 1, .);
for (c=1, c<=NItems(cols), c++,
clExpr = Column(dt, cols[c]) << getProperty("Control Limits");
avg_[c] = Arg(Arg(Arg(clExpr,1), 1), 1);
lcl_[c] = Arg(Arg(Arg(clExpr,1), 2), 1);
ucl_[c] = Arg(Arg(Arg(clExpr,1), 3), 1);
);
tb << Append(
ColSpanBox("Control Limits",
NumberColBox("Average", avg_),
NumberColBox("LCL", lcl_),
NumberColBox("UCL", ucl_),
)
);
```

But I suspect you knew that already!
