Dear QM gurus,
In the control charts which we get thru QGC1/2/3, can we set a 3 sigma limits ?
My customer wants the chart to be setup so that they can plot with 3 limits +/- with target line.
At the moment I can see in the chart is that limits can be changed only as below
upper action limit
upper warning limit
target
Lower warning limit
Lower action limit
Im looking for 1 more limit up and down, is this possible ?
Thanks
Mudassar
