How to access the table used to generate a change point detection plot

I'm using the change point detection feature in a multivariate parameter in my predictive analytics project, as shown in the graphic. I’m tracking the statistic but I can’t find a way to access the table used to generate the plot. Instead, I have to use the cursor to determine the values manually. A very labor-intensive process that does not lend to automation. I would appreciate any help I can get. Thanks.

Re: How to access the table used to generate a change point detection plot

You can get the X/Y values using JSL on the Marker Seg of the plot:

 

dt=Open("$SAMPLE_DATA/Quality Control/Steam Turbine Historical.jmp");
obj = dt<<Multivariate Control Chart(
	Y( :Fuel, :Steam Flow, :Steam Temp, :MW, :Cool Temp, :Pressure ),
	T Square Chart( 0 ),
	Principal Components( 0 ),
	Change Point Detection( 1 ),
	SendToReport( Dispatch( {}, "Scatterplot Matrix", OutlineBox, {Close( 1 )} ) )
);
rpt=obj<<Report;
frame=rpt[OutlineBox("Change Point Detection")][FrameBox(1)];
marker = frame<<Find Seg(MarkerSeg(1));
Show(marker << Get X Values(), marker << Get Y Values());
