How to make a dashboard public

[Ryan Lange]

I would like detailed information on how to make information public in a dashboard.

I'm new here, and I can not assign the "public" role to the dashboard.  Is there a system setting that I would need to change?

Is there a permission set that I would need to set to enable the "public" role?

Are there specific filters that would also need to be set to "public"?

Is there a specific group that uses non-authenticated users?

I've been searching the documentation, and I can find references to public, but I can't find it in the interface.

@Ryan Lange, 

You should check in your global settings to see if the settings allow for public sharing. Navigate to Administration -> System -> General Configuration. Edit the setting and look for "Public sharing".
