The SKYLINE series shows the four superior functions on the left (the Sunny Side of the skyline with the Sun above), and the four inferior functions on the right (the Shady Side of the skyline with the Moon above). This comes from the old idea of yin-yang, translated sometimes as the sunny (yang) side and shady (yin) side. You can see that the most favored functions (superior) are on the left (sunny side), and the least favored functions (inferior) are on the right (shady side). The #1 favorite function is shown in the tallest building at the far left , and the #1 least favorite function is shown in the tallest building on the far right.
