gitdot --png --msg --log-paths foo bar ^baz

means "list all the commits which are reachable from foo or bar, but not from baz".

A special notation <commit1>..<commit2> can be used as a short-hand for ^<commit1> <commit2>. For example, either of the following may be used interchangeably:

git log origin..HEAD git log HEAD ^origin
