formchar='B3,C4,DA,C2,BF,C3,C5,B4,C0,C1,D9'XAs an example, suppose you want to plot the data values of the empirical cumulative distribution function with asterisks (*). You can change the appropriate character using the following:
formchar(2)='*'Note that the FORMCHAR= option in the PROC CAPABILITY statement allows you to temporarily override the values of the SAS system option with the same name. The values of the SAS system option are not altered by using the FORMCHAR= option in PROC CAPABILITY statement.

proc capability round=1 0.5; var yldstren tenstren; run;When a variable value is midway between the two nearest rounded points, the value is rounded to the nearest even multiple of the roundoff value. For example, with a roundoff value of 1, the variable values of -2.5, -2.2, and -1.5 are rounded to -2; the values of -0.5, 0.2, and 0.5 are rounded to 0; and the values of 0.6, 1.2, and 1.4 are rounded to 1.
