Following on from my post on six sigma charts here, a discussion has opened up on QlikCommunity on moving the average once the n-points rule has been violated.

The problem is that the calculation for the average is iterative- once you work out a new average, the test for the points moves. This makes it tricky to achieve in the application, although it can be done in the script.
Any ideas anyone?
