If you want to put together heterogenous graphs (e.g. a bar chart and a box plot), I discuss a technique for doing this at the end of my "Secrets of the SGProcedures" paper (http://support.sas.com/resources/papers/proceedings09/324-2009.pdf). Take a look at that infomation and see if it helps.
To the OP: yours is a new query, suggest you not piggy-back on a query that was authored by someone else -- consider though adding a link in your forum post as an alternative to highlight relative content.
Also, your choice of forum is something else to consider next time - SAS/Graph has its own forum.
