I believe what you see for SAS/Graph output in the table of contents is the information that comes from the PLOT statement. The DESC= option might alter the contents label that you see. Also, the ODS PROCLABEL statement will make an impact on the top level node in the TOC. This note: http://support.sas.com/kb/11/888.html
Explains that in SAS 9.1, you cannot use DESC=' ' in order to "blank out" the description.
