To create additional graph templates, go to the SNAP! Options tab and select an existing template then click on the "Edit" button.

The graph setup lets you select how you want the response graphs to appear.

Any changes you make must be saved to the original template file using the 'Save' button, or to a new template using the 'Save As' button. Graph templates are saved as files with a ".gst" extension, and are saved to the folder that contains the SNAP.EXE program.
!! WARNING !! - Graph templates, including ones that you create or modify, are saved in files that are external to your PowerPoint file. When moving a presentation that uses SNAP! to another computer, be sure you copy and move any template files that you have created.
