PROBPLOT Statement

SYMBOL Statement Options

In earlier releases of SAS/QC software, graphical features of lower and upper specification lines and diagonal distribution reference lines were controlled with options in the SYMBOL2, SYMBOL3, and SYMBOL4 statements, respectively. These options are still supported, although they have been superseded by options in the PROBPLOT and SPEC statements. The following table summarizes the two sets of options:
