Google Analytics - Traffic Source (Defining Direct Traffic)

Hi,

I'm trying to do a pie chart of the traffic sources.  On my GA dashboard, it is able to distinguish between direct traffic and other sources.  

Direct traffic usually means "No Referral" since its accessed directly.  Using the "Full Referral" field, the data pulled down all has data which is mostly Google and Bing.  The "Referral Path" field list everything as (not set).  Please advise on a solution because its good to know if customers accessed the website directly compared searches or external sources.
