How to include code to show the Grid Lines in the Variability plot for X-Axis?

[#1]

Hi,

There is a list named "ColumnsList" with columns name from my Datatable for which i would like to make Variability plot for all columns present in the list.

Following Script creates box plots for all columns as required in the single page,

theExpr = "Variability Chart( Y( :\!"" || ColumnsList[1] || "\!"";
For( p = 2, p <= N Items( ColumnsList ), p++,
   theExpr = theExpr || ", :\!"" || ColumnsList[p] || " \!"");
theExpr = theExpr || "), X(:WaferID, :DateCode, :Die),Std Dev Chart( 0 ),Show Grand Mean( 1 )";
Eval( Parse( theExpr ) );

However, for me it is bit challenging to include a code snippet to include the "Show Major Grid" for X-Axis in the above script.

Could anyone help me, how to include code snippet to show the Major Grid Line in the above code.

Thank you.

Alex.

Maybe something like this:

Names Default To Here(1);
dt = Open("$SAMPLE_DATA/Variability Data/2 Factors Crossed.jmp");
var_chart = dt << Variability Chart(
	Y(:Measurement, :Standard), X(:Operator, :part#),
	Std Dev Chart(0),
	Show Grand Mean(1)
);

For Each({rep}, var_chart << report,
	axisbox = rep[axis box(2)];
	axisbox << Show Major Grid(1);
);
