PROC SHEWHART: Enhancing the Display of Signaled Tests

Enhancing the Display of Signaled Tests

There are various options for labeling points at which a test is signaled.

The default label for Test i is Testi. See Figure 15.181 for an example.
Specify TESTLABEL=SPACE to request labels of the form Test i. See Figure 15.182 for an example.
Specify TESTLABELi=’label’ to provide a specific label for the $\text{[math]}$ th test. See Figure 15.191 for an example.
Specify TESTLABEL=(variable) to request labels provided by a variable in the input data set. See Figure 15.184 for an example.

If two or more tests are signaled at a particular point, the label displayed corresponds to the test that was specified first in the TESTS= list.

If you are producing traditional graphics, you can specify the color of the label and the connecting line segments for the pattern with the CTESTS= option. You can specify the line type for the line segments with the LTESTS= option. If you are creating line printer charts, you can specify the plot character for the line segments with the TESTCHAR= option.

You can specify the ZONES option to display the zone lines on the chart, and you can specify ZONELABELS to label the zone lines. If you are creating traditional graphics, you can specify the color of the lines with the CZONES= option, and if you are producing line printer charts, you can specify the plot character for the lines with the ZONECHAR= option.
