A little background, for those not familiar with gtitle/nogtitle:
In traditional SAS/GRAPH (such as dev=png, using "ods html" output) ...
using the "ods gtitle" option causes the title to be part of the png file (ie, part of the graph), whereas "ods nogtitle" causes the title to be displayed as part of the html page, but outside of the png file (ie, as html text).
Device=activex and device=java versions of the SAS/GRAPHs do not support gtitles, therefore no matter which option you specify, they will only use 'nogtitle'.
When you run graphs through EG or Stored Processes, it's a little more difficult to control the gtitle/nogtitle.
To answer your question "how do I get rid of gtitle and gfootnote" ... totally get rid of the title (ie, no title text at all, neither in gtitle or nogtitle), you can simply blank out the title by giving a blank title statement:
