No, you're right, it's two pixels/sample - I was starting to run out 
of energy when working this out yesterday !

Not too useful when you have a table like this :

Address        In          Out
             Avg   Max   Avg   Max
x.y.z.1     n.n   n.n   n.n   n.n   foo.domain.com
x.y.z.2     n.n   n.n   n.n   n.n   foo.domain.com
x.y.z.254   n.n   n.n   n.n   n.n   foobar.domain.com

It can be damn hard working out which coloured area is which though, 
there just aren't 200+ distinct colours to use !
