Control Chart builder: why capability analysis disapear when the moving range graphic is removed?

flo_kussener

Hi,

 

I have a control chart built throught the control chart builder. as the variable has specification limits as property, the capability analysis is displayed.

 

If I remove the moving range graphics below the control chart (righ clic/remove), all the capability analysis on the right is also removed.

Why?
How to avoid that and continue to have the capability analysis even without the moving range graph?

Thank a lot,

Florence

It looks like a potential display problem/bug to me Florence. I get the same behaviour and I the refresh the display by clicking on the check box to show the points and then the capability analysis is redisplayed. If you need the points displayed then click on the display points check box again. It is not an ideal workaround, but it does work.

 

Best,
