Specification of the Distribution Reference Line

If you produce traditional graphics, you can control the color, type, and width of the diagonal distribution reference line by specifying the COLOR=, L=, and W= options in parentheses after the distribution option in the PPPLOT statement. Alternatively, you can control these features with the C=, L=, and W= options in the SYMBOL4 statement. Refer to SAS/GRAPH: Reference for details concerning these options. If you produce a line printer plot, you can specify the character used for the line with the SYMBOL= option enclosed in parentheses after the distribution option in the PPPLOT statement.
