The SHEWHART Procedure


Dictionary of Options: SHEWHART Procedure

The section provides detailed descriptions of options that you can specify in the following chart statements:

  • BOXCHART

  • CCHART

  • IRCHART

  • MCHART

  • MRCHART

  • NPCHART

  • PCHART

  • RCHART

  • SCHART

  • UCHART

  • XCHART

  • XRCHART

  • XSCHART

Options are specified after the slash (/) in a chart statement. For example, to request tests for special causes with an $\bar{X}$ and R chart, you can use the TESTS= option as follows:

proc shewhart data=Measures;
   xrchart Length*Sample / tests=1 to 4 ;
run;

The options described in these sections are listed alphabetically. For tables of options organized by function, see the "Summary of Options" tables in the sections for the various chart statements.

Unless indicated otherwise, the options listed here are available with every chart statement. For statements that create two charts, the term primary chart refers to the upper chart (for instance, the $\bar{X}$ chart created with the XRCHART statement), and the term secondary chart refers to the lower chart (for instance, the R chart created with the XRCHART statement). The term primary chart also refers to the single chart created by some statements (for instance, the p chart created with the PCHART statement).

The section General Options contains descriptions of general chart statement options, which are applicable regardless of the kind of graphics output you produce. The section Options for ODS Graphics describes options that apply only when ODS Graphics is enabled. The section Options for Traditional Graphics describes options that apply only when producing traditional graphics, as when ODS Graphics is disabled. The section Options for Legacy Line Printer Charts contains descriptions of options that apply only to legacy line printer charts, which are produced when the LINEPRINTER option is specified in the PROC SHEWHART statement.
