PROC SHEWHART: Specifying the Style of Stars

The SHEWHART Procedure

Specifying the Style of Stars

[See SHWSTR2 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:

symbol v = none;
title 'Variables Related to Paint Index';
proc shewhart history=paint limits=paintlim;
   xchart pindex * hour /
      nolegend
      starvertices = ( thick gloss defects dust humid temp )
      starstart    = '1:00'T
      startype     = wedge;
   xchart pindex * hour /
      nolegend
      starvertices = ( thick gloss defects dust humid temp )
      starstart    = '1:00'T
      startype     = radial;
   xchart pindex * hour /
      nolegend
      starvertices = ( thick gloss defects dust humid temp )
      starstart    = '1:00'T
      startype     = spoke;
   xchart pindex * hour /
      nolegend
      starvertices = ( thick gloss defects dust humid temp )
      starstart    = '1:00'T
      startype     = corona;
run;

The charts are shown in Figure 13.43.43, Figure 13.43.44, Figure 13.43.45, and Figure 13.43.46. The default style for the stars is STARTYPE=POLYGON, which is illustrated in Figure 13.43.41 and Figure 13.43.42. For more information, see the entry for the STARTYPE= option in Dictionary of Options

Output 13.43.43 Star Chart Using STARTYPE=WEDGE

Output 13.43.44 Star Chart Using STARTYPE=RADIAL

Output 13.43.45 Star Chart Using STARTYPE=SPOKE

Output 13.43.46 Star Chart Using STARTYPE=CORONA
