I finally made a graph with enneagram triads:
First triad is head/heart/gut. Sine waves peak at the crowns of each triad and bottom out at the point diametrically opposed to the crown of each triad.
Second triad is double the frequency of the first triad. Every point on the enneagram wheel is the same and the opposite of every point diametrically opposed to it; this is how they are the same, the crowns of the triads are how they are opposite.
Third triad is triple the frequency of the first triad. More on the way soon, gonna sleep first
