INSET and INSET2 Statements

Overview

The INSET and INSET2 statements enable you to enhance a Shewhart chart by adding a box or table (referred to as an inset) of summary statistics directly to the graph. The INSET statement places an inset in a primary Shewhart chart while the INSET2 statement places one in a secondary Shewhart chart. An inset can display statistics calculated by the SHEWHART procedure or arbitrary values provided in a SAS data set.

Note that an INSET or INSET2 statement by itself does not produce a display but must be used in conjunction with a chart statement. Insets are not available with line printer output, so the INSET and INSET2 statements are not applicable when the LINEPRINTER option is specified in the PROC SHEWHART statement.

You can use options in the INSET and INSET2 statements to

The INSET2 statement differs from the INSET statement in only two respects.

  1. An INSET2 statement creates an inset within a secondary chart generated by an IRCHART, MRCHART, XRCHART or XSCHART statement or by the TRENDVAR= option. For example, when following an XRCHART statement an INSET statement produces an inset in the \bar{X} chart and an INSET2 statement produces one in the R chart.
  2. The INSET statement can be used to place an inset in one of the margins surrounding the plot area, while the INSET2 statement cannot.
Any of the statistics available for display in an inset can be specified with either an INSET or INSET2 statement. Descriptions of the INSET statement in this chapter also apply to the INSET2 statement except where explicitly noted.
