Hi,
I have a strange behavior when I want to filter a control chart with Alarm (Test2, 3, etc).
imagine you have the following control chart. My alarms are active and it is ok!

But what if now I filter?
I have less data so Test 2 (9 consecutive point on one side), or 3 (6 Increasing/decreasing points) should appear less. it is not true, it appears as if we have all the data!!!!


it is really an unexpected behavior!!!
any workaround???? -> Except split the data and use the column switcher which generates me another abnormal behavior (see my following post!!!)
Thank a lot,
Florence
Florence, it seems the warnings are calculated for the whole column. You can see this if you uncheck the "show" check-box for the data filter. Not sure if this si a bug or expected behaviour. This have to answer other people:)
