Hi...one way to avoid color cycling (and force SAS/Graph to choose
different symbols)...

goptions csymbol=black;

You can still write SYMBOL statements (as you've shown), but you can leave
out the COLOR specification in each one.

I don't know of a way to change the automatic assignment but each plot
line can be explicitly set.  Try placing something like the following
lines before the plot statement.

symbol1 c=black v=diamond;
symbol2 c=black v=star;
symbol3 c=black v=square;
symbol4 c=black v=x;
symbol5 c=black v=triangle;
symbol6 c=black v=hash;
symbol7 c=black v=dot;
symbol8 c=black v=circle;
symbol9 c=black v=(;
symbol10 c=black v=/;
