On a control chart, how can I show an excluded point without having it connected by a line to the non-excluded points?
Unfortunately, that's not currently possible.
I'll note the request and we'll consider it for an enhancement in a future release.

Jeff,
Thanks for getting back to me. I expected as such. We’ve actually gotten around that with a script that extracts the control limits from column properties, then uses graph builder to plot to Y variables, one with points and a line, the other with just points, with the control limits inserted as reference lines.

Another possible workaround could be to use a graphics script to show the excluded points. An example:
dt = Open("$SAMPLE_DATA/Quality Control/Coating.jmp");
// Hide and exclude some rows
dt << select rows([13, 17]) << exclude << hide << clear select();
cc = dt << Control Chart(Sample Size(1), Chart Col(:Weight, Run Chart()), );
//Add markers for the excluded data
r = dt << get excluded rows;
Eval(Eval Expr(Report(cc)[Framebox(1)] << add graphics script(Marker(Expr(r), Expr(:Weight[r])))));
Thanks! That was helpful, but two things come to mind … First, is there a way to use as logical expression to select the rows to hide based on values of another column? Second, I’ve discovered I did not completely specify my question (sorry about that)! I also wanted to show the excluded points with a different symbol, so is there a way to add something to the script that changes the marker for those excluded points?
PS., I was going to post this as another reply, but it seems there are “no actions available” on my discussion.
