CUSUM Chart

The CUSUM Chart report contains the cumulative sum control chart with decision limits that are determined by the current values of the chart parameters. The samples (or subgroups if you specified an X variable) are denoted on the horizontal axis. The vertical axis denotes centered values of the positive and negative values for the cumulative sum. If the Data Units option was not selected in the launch window, the vertical axis denotes cumulative sums for standardized response values. If the Data Units option was selected in the launch window, the vertical axis denotes cumulative sums for unstandardized response values.
