Box plot show Different Spec line in a graph by JSL

[#1]

As the document 《P1 CAN.jmp》, the graph  "FAI 19-Flange" box plot is created by 《Direct create Boxplot.jsl》, this method does not need to stack data table, but the Spec line is the same Horizontal line. Now, I want to show it as 《Box Plot.jpg》by Different Spec line, and this method was created by manual operation, it needs to stack data table, how to correct 《Direct create Boxplot.jsl》can auto create?

Is this what you want

names default to here(1);
dt = current data table();
colNamesX = dt << get column names(string);
for(i=nitems(colNamesX),i>=1,i--,
	if(contains(colNamesX[i],"Flange")==0,
		remove from(colNamesX,i,1),
		word(4,colNamesX[i],"-.")!="",
			remove from(colNamesX,i,1)
	)
);
colNameColor = column(1)<<get name;

theExpr =
"gb = dt << Graph Builder(
	Size( 534, 464 ),
	Show Control Panel( 0 ),
	Variables(";
for each( {col,index}, colNamesX,
	theExpr = theExpr || 
		"X( :\!"" || col || "\!"n, Position( 1 ) ),";
);
theExpr = theExpr ||
	"Color( :\!"" || colNameColor || "\!"n )
	),
	Elements(
		Box Plot(";
for each( {col,index}, colNamesX,
	theExpr = theExpr || 
		"X( " || char(index) || " ),";
);
theExpr = theExpr ||
	"Legend( 3 )
		),
		Points(";
for each( {col,index}, colNamesX,
	theExpr = theExpr || 
		"X( " || char(index) || " ),";
);
theExpr = theExpr ||
	"Legend( 4 )
		)
	)
);";

// Generate the graph
eval(parse(theExpr));

// Add the USL line
// Find the USL row
theUSLRow = (dt << get rows where(:Phase == "USL"))[1];

// Get the values
USLs = [];
For Each( {col}, colNamesX,
	USLs = USLs || matrix(as column(dt,col)[theUSLRow])
);

// Set the Y axis upper value
report( gb )[AxisBox(2)] << Max(max(USLs)+.1*(max(USLs)-(report( gb )[AxisBox(2)] << get min)));

report( gb )[FrameBox(1)] << Add Graphics Script(
	Pen Color( "red");
	Pen Size( 2 );
	Line Style( "DashDot");
	
	matX = [];
	For(i=0,i<=length(USLs)-1,i++,
		matX = matX || matrix(i-.5) || matrix( i+.5);
	);
	matY = [];
	For(i=1,i<=length(USLs),i++,
		matY = matY || USLs[i] || USLs[i];
	);
	Line(matX,matY);
	Text Color( "red" );
	textPos = {0};
	insert into(textPos,Max(max(USLs)+.025*(max(USLs)-(report( gb )[AxisBox(2)] << get min))));
	Text( Center Justified, eval(textPos), "USL" );
);
