During runtime, when SPC is in Exclusion Mode, an operator can exclude one or more samples from calculation. An operator can also re-include samples.
As soon as you toggle the exclusion state of a sample, SPC immediately recalculates the control limits displayed on the chart.
The following symbols allow you to view exclusion status.
X |
In the upper left-hand corner of the SPC control chart |
Exclusion mode is on. |
l |
Represents a sample |
Sample is included in the calculation. |
X |
Represents a sample |
Sample is excluded from calculation. |
To exclude samples from a control chart when SPC is in Exclusion Mode:
Do one of the following.
Method 1
Click on a dot that represents the sample to toggle its exclusion state.
Result: The dot will change to an X indicating that the sample is excluded.
Method 2
Click on a corner of the group of sample to be excluded.
Drag the cursor over the entire groups of samples. Note that a box will appear around the selected samples.
Release the mouse button.
Result: Each dot that represented an included sample changes to an X, indicating the sample is now excluded.
Note: The GetControlLimits() ActiveX method provides access to the control limits displayed on the chart.
