I get the concept. What I can't seem to wrap my head around is the  
specifics of how these statements fit together. If I had an example  
rrdgraph statement to look at that used these statement, it would  
help. I can't seem to find documentation that I can make heads or  
tails of or any examples. I even downloaded Router2 to try and look,  
but the programming there is way above me and I couldn't seem to pull  
out the relevant pieces.

What I need is a concrete example to see and then go from there
