The MACONTROL Procedure


Syntax: INSET Statement

The syntax for the INSET statement is as follows:

  • INSET keyword-list </ options>;

You can use any number of INSET statements in the MACONTROL procedure. However, when ODS Graphics is enabled, at most two insets are displayed inside the plot area and at most two are displayed in the chart margins. Each INSET statement produces a separate inset and must follow an EWMACHART or MACHART statement. The inset appears on every panel (page) produced by the last chart statement preceding it.

Keywords specify the statistics to be displayed in an inset; options control the inset’s location and appearance. A complete description of the INSET statement syntax is given in the section Syntax: INSET and INSET2 Statements of Chapter 17: The SHEWHART Procedure. The INSET statement options are identical in the MACONTROL and SHEWHART procedures, but the available keywords are different. The options are listed in Table 17.88. The keywords available with the MACONTROL procedure are listed in Table 9.14 to Table 9.17.
