The SHEWHART Procedure

Note: See Star Charts-Specifying the Style of Stars in the SAS/QC Sample Library.

The following statements create star charts for paint index using different styles for the stars specified with the STARTYPE= option:

ods graphics on;
title 'Variables Related to Paint Index';
proc shewhart history=Paint limits=Paintlim;
   xchart pindex * hour /
      nolegend
      odstitle     = title
      starvertices = ( thick gloss defects dust humid temp )
      starstart    = '1:00'T
      startype     = wedge;
   xchart pindex * hour /
      nolegend
      odstitle     = title
      starvertices = ( thick gloss defects dust humid temp )
      starstart    = '1:00'T
      startype     = radial;
   xchart pindex * hour /
      nolegend
      odstitle     = title
      starvertices = ( thick gloss defects dust humid temp )
      starstart    = '1:00'T
      startype     = spoke;
   xchart pindex * hour /
      nolegend
      odstitle     = title
      starvertices = ( thick gloss defects dust humid temp )
      starstart    = '1:00'T
      startype     = corona;
run;

The charts are shown in Figure 17.160, Figure 17.161, Figure 17.162, and Figure 17.163. The default style for the stars is STARTYPE=POLYGON, which is illustrated in Figure 17.158 and Figure 17.159.
