I've written this chart out up to the 12th fret. After the 12th fret, 
it just repeats itself. I noticed a little thing that might be really 
useful to remember as I was writing this out too:
Say you are playing in E...the 3 main major chords 
in this key are E, A and B. 

These are the 1st, 2nd and 5th notes if you pick all strings open.
This is the same for every other key! Look at the diagram 
to get a better idea of what I'm talking about. 
Key of Ab, for instance. Main chords are Ab, Db and Eb.
See what I mean??? This is really useful for playing in keys 
you are unfamiliar with.  Hope all this helps!
