Using Excel, you can select the labels and data for your chart and use Paste Special to paste a link into another sheet (in this case the template input area). This may work for you, however, Excel treats blanks as zeros which can be a problem. Also, Excel won't allow you to paste link and transpose data. Such a control chart has a constant center line at 0, and upper and lower control limits of +3 and -3 respectively making patterns easier to spot. Tests 1, 5, 6, 2 are defined by the Western Electric CO (1958) as the original 4 rules. Tests 1-8, with the modification of test 2 to from 8 to 9 points, are defined by Lloyd S. Nelson (1984). There are four Western Electric rules for control charts. Western Electric Rules are the original set of four control chart rules used to conduct stability analysis. Western Electric Rules can be used with all control charts and are sometimes referred to as WECO Rules. One point above UCL or below LCL. Nelson Rules for Control Charts. Nelson rules include the four Western Electric rules plus four more. Nelson Rules were developed in the 1950s and can be used with any control chart. One point above UCL or below LCL. Two points above/below 2 sigma. Three out of four points above/below 1 sigma.

Out of Control Tests Review One of our publications examined the 8 rules that you can use to help you interpret what your control chart is communicating to you. These rules help you identify when the variation on your control chart is no longer random, but forms a pattern that is described by one or more of these eight rules. Control Chart Rules, Patterns, and Interpretation ➝ Control Chart Rules, Patterns, and Interpretation are helping us to identify the special cause of variation from the process. ➝ By referring to these 8 rules, we can identify and eliminate the cause of variation and make our operation smooth. The same is true for zones B and C. Control charts are based on 3 sigma limits of the variable being plotted. Thus, each zone is one standard deviation in width. For example, considering the top half of the chart, zone C is the region from the average to the average plus one standard deviation.
Control chart rules are then applied to data points as they move through those zones. Unstable points and trends are identified for investigation. QI Macros highlights unstable points and trends by turning them red.

This may work for you, however, Excel treats blanks as zeros which can be a problem. Also, Excel won't allow you to paste link and transpose data.
Control rules take advantage of the normal curve in which 68.26 percent of all data is within plus or minus one standard deviation from the average, 95.44 percent of all data is within plus or minus two standard deviations from the average, and 99.73 percent of data will be within plus or minus three standard deviations from the average.

Create Control Charts (X-Bar & R Chart) in Excel - Duration: 16:39. Quality HUB India 154,895 views Control Chart Basic Procedure Choose the appropriate control chart for your data. Determine the appropriate time period for collecting and plotting data. Collect data, construct your chart and analyze the data. Look for "out-of-control signals" on the control chart. Continue to plot data as they Control rules take advantage of the normal curve in which 68.26 percent of all data is within plus or minus one standard deviation from the average, 95.44 percent of all data is within plus or minus two standard deviations from the average, and 99.73 percent of data will be within plus or minus three standard deviations from the average. The individuals control chart uses an estimated standard deviation from the range chart to determine the control limits. In addition, the individuals chart uses the average of the results for the center line while the Levey-Jennings chart uses either the average or the control value for the center line.
