Shewhart p-chart for attribute (Sigma)

Hi expert,

 

Is there any way to display the calculated sigma (from binomial distribution) in this limit summaries of p-chart for attribute?

WebDesignesCrow_0-1674808906180.png

Note: I can calculate it manually by using the formula or reverse mathematical operation but rather than work in Excel, I would like to display it on the JMP limit summaries?

 

Thanks! (I'm using JMP 15)

Re: Shewhart p-chart for attribute (Sigma)

If Sigma Report isn't enough, you can use Insert Into to add new Number Col Box to the Limit Summaries table box

Names Default To Here(1);
dt = Open("$SAMPLE_DATA/Probe.jmp");

obj = dt << Control Chart Builder(
	Show Two Shewhart Charts(0),
	Show Sigma Report(1),
	Variables(Y(:DELL_RPNBR), Phase(:Process)),
	Chart(Points(Statistic("Moving Range")), Limits(Sigma("Moving Range"))),
	Show Control Panel(0)
);

tb = Report(obj)["Control Chart Builder","DELL_RPNBR Limit Summaries",TableBox(1)];
// get/calculate sigma values...
sigma_values = [3,4];
Insert Into(tb, Number Col Box("Sigma", sigma_values), 5);
