Control limit calculations for Run Charts differ depending upon your default selections for the Process Chart. Depending upon which of the following charts you have selected as your default Individual Chart, the control limits will be calculated using one of the formulas below:

XMR(2) Chart | XMR(3) Chart | RX Chart
`IXUCL = x + 2.660x` | `IXUCL = x + 1.772x` | `IXUCL = x + 2.660x`
`IXLCL = x - 2.660x` | `IXLCL = x - 1.772x` | `IXLCL = x - 2.660x`
