If you produce traditional graphics, you can use options in the SYMBOL1 statement to specify the appearance of the symbol marker for the points. The V= option specifies the symbol, the C= option specifies the color, and the H= option specifies the height. Refer to SAS/GRAPH: Reference for details concerning these options. If you produce a line printer plot, you can use the PPSYMBOL= option in the PPPLOT statement to specify the character used to plot the points.
