INSET Statement: CAPABILITY Procedure

Overview: INSET Statement

Graphical displays such as histograms and probability plots are commonly used for process capability analysis. You can use the INSET statement to enhance these plots by adding a box or table (referred to as an inset) of summary statistics directly to the graph. An inset typically displays statistics calculated by the CAPABILITY procedure but can also display values provided in a SAS data set. A typical application of the INSET statement is to augment a histogram with the sample size, mean, standard deviation, and process capability index $\text{[math]}$ .

Note that the INSET statement by itself does not produce a display and must be used with the CDFPLOT, COMPHISTOGRAM, HISTOGRAM, PPPLOT, PROBPLOT, or QQPLOT statement. ¹

You can use options in the INSET statement to

specify the position of the inset
specify a header for the inset table
specify graphical enhancements, such as background colors, text colors, text height, text font, and drop shadows

The INSET statement is not applicable when you produce line printer plots by specifying the LINEPRINTER option in the PROC CAPABILITY statement.

Footnotes

In SAS 6.12 and in previous releases of SAS/QC software, the keyword GRAPHICS was required in the PROC CAPABILITY statement since the INSET statement only applies to graphical output.
