Control Chart special cause labels are offset?

Hi all. Anyone know how to correct this? My flags to indicate a process shift are offset from the actual data-points. Never had this before.

Re: Control Chart special cause labels are offset?

It sounds like this is something special that happens only with this data set since you say you have not had this happen before.  I suggest sending the example or something similar to technical support so they can investigate further.

Re: Control Chart special cause labels are offset?

Thanks Tonya. With 77 views at time of writing and not even a hint of possible solutions, that's enough to know this is a rare occurrence. I have since figured out that the more data points I exclude from the calculation of the spec limits, the less offset I observe. This is a workaround though and doesn't explain what's actually happening. I will raise with technical support as you suggest. Many thanks.
