Control Chart Template - Center Line Based on Average

The QI Macros default control chart template uses the average of your data to calculate the center line on your control chart. The 1 and 2 sigma lines and the upper and lower control limits are derived from this average.

To use a control chart template:

1. Click on the QI Macros menu and Control Chart Templates.
   
2. Click on one of the control chart templates to open it (e.g. XmR, XbarR, XbarS, Levey Jennings.)
3. The control chart using the average line is the default and is usually the worksheet that is the farthest tab to the left (e.g. XmR Individuals Chart.)
   
4. Data input areas are shaded in yellow. As you input data, the charts populate to the right.
   
   
   
5. The X chart templates have input areas to define spec limits for the histogram.
