Chart Windows
The content of chart windows is specific for the type of chart you have
created, as specified in the Chart Options dialog box, but there are a number of
features common to the various charts.
Chart window’s interface
- Several Chart Symbols are used to indicate warning and audit conditions
- Zoom and Pan in the Chart window to view charts with lots of data in greater detail.
- Left Mouse button selection of a subgroup provides basic subgroup information
- Right Mouse button selection of a subgroup provides the following options:
- Go To Data: to go to the Data Editor at the selected subgroup
- Drop from Chart: to remove the selected subgroup from the analysis.
- Assignable Cause: to attach an Assignable Cause to the selected subgroup.
- Show the Statistics window as a split screen below the control chart by
selecting Show Statistics from the Edit menu, or check the Statistics check box on
the Chart Options dialog box .
Note: MS Windows 3.1 and Windows 95 restrict the Statistics window to
approximately 32,000 characters.

x-axis and y-axis labels with specified fonts and colors, and change scaling

file.

- Produce alert messages (such as for advising corrective action), and highlight points, when control
limits are exceeded, run tests are violated, capability goes below a threshold,
or specs are exceeded by specifying these in the Analysis Options dialog box.
Options affecting the mathematics of the Analysis

recalculations using the Recalc button on a Chart or Statistics window. The check mark is toggled on and off
whenever you click on the menu item. The default state for the Auto
Recalculation option may be set in the Preferences dialog from the Options menu.
