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:
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 17.159, Figure 17.160, Figure 17.161, and Figure 17.162. The default style for the stars is STARTYPE=POLYGON, which is illustrated in Figure 17.157 and Figure 17.158.
