LSCX = UCLX = upper control limit for X Chart = Xm + A2 * R LICX = LCLX = lower control limit for X Chart = Xm - A2 * R where Xm = X

LSCR = upper control limit for R Chart = D4 * R LICR = lower control limit for R Chart = D3 * R

The x and y points of the gaussian chart are calculated as follows:

x = t * S + X

t is a parameter that goes from -4 to +4 step 0,1

It displays the detected values in a chart together with Project Upper Limit (LSS), Project Lower Limit (LIS) and the Target Value.

It displays graphically the values included in each subgroup. When the grouping criteria is 1 it overlaps to the control chart.
