Some shapes leave out: 5th (G). The caption of each one says what is missing. The 5th is the first to go: it barely changes the sound of the chord.

Numbers are fingers: 1 index, 2 middle, 3 ring, 4 pinky. x = do not play the string, o = open string. The coloured dot is the root (C). The same shapes work on acoustic, classical and electric guitar.
