Delete a Point from a Control Chart
Remove Point from a Chart and from Control Limit Calculations
It's easy to delete a point from a control chart created using QI Macros. The process is different depending on how you create your control chart:
- Control Charts Created with a Macro
- Control Charts Created Using Control Chart Templates
- Excel 2007 Workaround for Deleting a Point on an Embedded Chart
To delete a point from a control chart:
- Click on the chart.
- Click on the point you want to delete.
Tip: The first time you click on a point, Excel will select the whole line. Click on the point a second time to select just the point. If you have done this correctly, Excel will highlight your point.
- Click on the QI Macros Chart menu (to the far right) to open the control chart tools menu. Select "Ghost,Delete or Show Point" then Delete point..
- Rerun stability analysis without the deleted point by selecting "Analyze Stability" on the same menu.
To delete a point on a control chart template, simply delete that point from the input area.
NOTE: If you use the "Delete Point" function from the QI Macros Chart section, the function will remove necessary calculations from your template.
