INSET Statement
INSET <keyword-list> </ options> ;

The box or table of summary information produced on plots made with the PROBPLOT statement is called an inset. You can use the INSET statement to customize the information that is displayed in the inset box as well as to customize the appearance of the inset box. To supply the information that is displayed in the inset box, you specify keywords corresponding to the information that you want shown. For example, the following statements produce a probability plot with the number of observations, the number of right-censored observations, the name of the distribution, and the estimated Weibull shape parameter in the inset:

   proc lifereg data=epidemic;
      model life = dose / dist = Weibull;
      probplot ;
      inset nobs right dist shape;

By default, inset entries are identified with appropriate labels. However, you can provide a customized label by specifying the keyword for that entry followed by the equal sign (=) and the label in quotes. For example, the following INSET statement produces an inset containing the number of observations and the name of the distribution, labeled "Sample Size" and "Distribution" in the inset:

   inset nobs='Sample Size' dist='Distribution';

If you specify a keyword that does not apply to the plot you are creating, then the keyword is ignored.

If you specify more than one INSET statement, only the first one is used.

Table 50.2 lists keywords available in the INSET statement to display summary statistics, distribution parameters, and distribution fitting information.

Table 50.2 INSET Statement Keywords




Confidence coefficient for all confidence intervals


Name of the distribution


Number of interval-censored observations


Number of left-censored observations


Number of observations


Number of observations with missing values


Number of right-censored observations


Value of the scale parameter


Value of the shape parameter


Number of uncensored observations

The following options control the appearance of the box when you use traditional graphics. These options are not available if ODS Graphics is enabled. All options are specified after the slash (/) in the INSET statement.


specifies the color for the filling box.


specifies the color for the filling box header.


specifies the color for the frame.


specifies the color for text in the header.


specifies the color for the text.


specifies the software font for the text.


specifies the height of the text.

HEADER=’quoted string’

specifies the text for the header or box title.


omits the frame around the box.


determines the position of the inset. The value can be a compass point (N, NE, E, SE, S, SW, W, NW) or a pair of coordinates (x, y) enclosed in parentheses. The coordinates can be specified in screen percentage units or axis data units. The default is screen percentage units.


specifies the reference point for an inset that is positioned by a pair of coordinates with the POS= option. You use the REFPOINT= option in conjunction with the POS= coordinates. The REFPOINT= option specifies which corner of the inset frame you have specified with coordinates (x, y), and it can take the value of BR (bottom right), BL (bottom left), TR (top right), or TL (top left). The default is REFPOINT=BL. If the inset position is specified as a compass point, then the REFPOINT= option is ignored.
