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

The box or table of summary information produced on plots made with the CDFPLOT, IPPPLOT, LPREDPLOT, or PREDPPLOT statement is called an inset. You can use the INSET statement to customize both the information that is printed in the inset box and the appearance of the inset box. To supply the information that is displayed in the inset box, you specify keywords corresponding to the information you want shown. For example, the following statements produce a predicted probability plot with the number of trials, the number of events, the name of the distribution, and the estimated optimum natural threshold in the inset.

proc probit data=epidemic;
   model r/n = dose;
   predpplot ;
   inset nobs ntrials nevents dist optc;
run;

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.

The options control the appearance of the box.

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

Keywords Used in the INSET Statement

Table 74.8 and Table 74.9 list keywords available in the INSET statement to display summary statistics, distribution parameters, and distribution fitting information.

Table 74.8 Summary Statistics

NOBS

Number of observations

NTRIALS

Number of trials

NEVENTS

Number of events

C

User-input threshold

OPTC

Estimated natural threshold

NRESPLEV

Number of levels of the response variable

Table 74.9 General Information

CONFIDENCE

Confidence coefficient for all confidence intervals

DIST

Name of the distribution

Options Used in the INSET Statement

Table 74.10 and Table 74.11 list the options available in the INSET statement.

Table 74.10 Color and Pattern Options

CFILL=color

Specifies color for filling box

CFILLH=color

Specifies color for filling box header

CFRAME=color

Specifies color for frame

CHEADER=color

Specifies color for text in header

CTEXT=color

Specifies color for text

Table 74.11 General Appearance Options

FONT=font

Specifies software font for text

HEIGHT=value

Specifies height of text

HEADER=’quoted string’

Specifies text for header or box title

NOFRAME

Omits frame around box

POS= value

 

<DATA | PERCENT>

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 axis percentage units or axis data units.

REFPOINT= name

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.
