Defining Control Charts
To define control charts, use the Control Charts component (QS_CL_CHART). This topic discusses how to define control charts.
Pages Used to Define Control Charts
| Page Name | Definition Name | Usage |
|---|---|---|
|
QS_CL_CHART0 |
Define the scope of the chart, such as chart prototype and testing zones. Use these charts for real-time or offline data analysis. |

QS_COPY0_PNL |
Creates a new chart by copying an existing chart. |
Defining Control Chart Page
Use the Define Control Chart page (QS_CL_CHART0) to define the scope of the chart, such as chart prototype and testing zones.

Click the Copy From button to create the new control chart by copying from an existing control chart. When you click this button, the Copy Configuration Item page appears. |
|
Chart Prototype |
Select a chart prototype. Values are: X & Moving Range, Xbar & Range, Xbar & Sigma, c Chart, np Chart, p Chart, and u Chart. The chart prototype that you select defines the standard formulas that are used to calculate subgroup values and control limits. |
|
Test Zones |
Enter the number of divisions between the upper control limit (UCL) and the mean (CL) limit lines that are used for control-test evaluations. Zones typically represent standard deviations. |
|
Data Type |
Select the type of data that is to be plotted on this chart. Values include: Variables: Measurable characteristics, such as length, mass, or time, and for characteristics that are derived from measurable characteristics, such as volume, density, or area. Defects: Characteristics that represent defect counts, which are counts of the number of defects observed per unit, such as scratches, blemished, or missing subcomponents. Defectives: Characteristics that represent counts of defective units and counts of how many units are defective using a pass or fail criteria. |
