The following are the primary statements that control the SHEWHART procedure:

PROC SHEWHART <options> ;

BOXCHART (processes) * subgroup-variable <(block-variables)> <=symbol-variable | 'character'> < / options> ;

CCHART (processes) * subgroup-variable <(block-variables)> <=symbol-variable | 'character'> < / options> ;

IRCHART (processes) * subgroup-variable <(block-variables)> <=symbol-variable | 'character'> < / options> ;

MCHART (processes) * subgroup-variable <(block-variables)> <=symbol-variable | 'character'> < / options> ;

MRCHART (processes) * subgroup-variable <(block-variables)> <=symbol-variable | 'character'> < / options> ;

NPCHART (processes) * subgroup-variable <(block-variables)> <=symbol-variable | 'character'> < / options> ;

PCHART (processes) * subgroup-variable <(block-variables)> <=symbol-variable | 'character'> < / options> ;

RCHART (processes) * subgroup-variable <(block-variables)> <=symbol-variable | 'character'> < / options> ;

SCHART (processes) * subgroup-variable <(block-variables)> <=symbol-variable | 'character'> < / options> ;

UCHART (processes) * subgroup-variable <(block-variables)> <=symbol-variable | 'character'> < / options> ;

XCHART (processes) * subgroup-variable <(block-variables)> <=symbol-variable | 'character'> < / options> ;

XRCHART (processes) * subgroup-variable <(block-variables)> <=symbol-variable | 'character'> < / options> ;

XSCHART (processes) * subgroup-variable <(block-variables)> <=symbol-variable | 'character'> < / options> ;

INSET keyword-list < / options> ;

INSET2 keyword-list < / options> ;

The PROC SHEWHART statement invokes the procedure and specifies the input data set. The chart statements create different types of control charts. You can specify one or more of each of the chart statements. For details, read the section on the chart statement that corresponds to the type of control chart you want to produce.
