Don't know of a chart, but here is my 2 cents....

The Ctenochaetus and Naso genus are the least aggressive, Naso obviously being very large as adults.

Zebrasoma can certainly be highly territorial, and tricky to keep together, Yellows and Purple often work in odd numbers (3 and 5).

The Acanthurus genus tend to be real nasties, some being much worse than others. In a long list of Triggers, Angels, and Wrasses I've kept, the 2 most dominant fish I've kept have both been Acanthurus (Sohal and Achilles). Mixing this genus is not advised unless a huge tank, and should typically be the last Tang added and often the last fish added.
