Capability analysis in Control Chart builder

DSA

Dear JMP community,

i am playing a bit with the control chart builder and the capability analysis when I have control limits on the column i am looking at.

I am doing a Levey Jennings control chart, where i hide the moving range since we do not normally look at it - but when i remove the moving range plot the process capability analysis is removed from the output as well.

Is there a way to force it to show a Level Jennings control chart without a moving range plot but still showing the process capability analysis?

I am getting the same issue in both JMP 13.2 and 14.1.

Thanks in advance,

Daniel

There appears to be a bug. After I removed the Moving Range Chart, just as you indicated, the Capability Analysis went away. However, I then clicked off the Spec Limits check box and the Capability Analysis reappeared.

Thanks Jim, I can recreate what you are seeing.

I'll report it - thanks!

This is a problem with the software and the developers are working on a correction. Another work around for the problem that allows you to keep both the spec limits and the capability analysis is to turn off the points in the graph (an option in the control panel) and then turn them back on again.

Thanks for the confirmation Susan.

Is it possible to click and unclick this button via JSL? I am quite sure that i cannot get my end-users to do it.

But if I could script it, that would be a solution for me.

Thanks,

Daniel
