Hi:
Look at the examples of the BAND chart on page 2 of this paper. That should give you some ideas to get started:
http://support.sas.com/resources/papers/proceedings09/324-2009.pdf (which uses the SG Procedures)
or this example that uses PROC GPLOT from Rob Allison's SAS/Graph site:

or this:

For ideas of all that is possible with SAS/Graph, I highly recommend Bob Allison's web site as you need proof of concept. It shows the breadth and depth of all that is possible with SAS/GRAPH traditional and new procedures:
