Hey ll_flw
Which one you have trouble with, the rectangular looking one or the round one?
Anyhow... i think they are both very similar....
Let me try to explain it with the round one.
Imagine you are standing in the centre of it.
The curve lines that has (May21, July 21...) that showing you the path of the sun travel in that month/date
the intersect lines show the time (6 am till 6 pm... )
The circles indicate the azimuth & altitude
Let say you are in the centre and you want to find out where the sun will be at 1pm on Jul 21st.
1. you find the curve that's represent Jul 21\
2. find the intersection of 1pm & that line
3. read the angles (straight line is the NSEW, and the circles will give you the degree from horizon)
Does that make any sense??
Anyhow, while I am trying to explain.. here's one website... you might want to take a look at as well.

Good luck.

I had 2 solar questions that had an odd diagrams that I have never seen before. I skipped them and came back to figure them out. It wasnt difficult, but I had to take the time to figure out the backwards sketches. They could have easily asked the same questions using a typical solar path chart, but no, they needed to resort to trickery.

Now, now. I'm sure it was the same chart that the Mayans carved into the sides of their temples to chart the course of the sun on Summer and Winter Solstice.

from my vague recollection, the one I encountered was essentially a circle with a tangent line. this tangent line was the horizon. it showed a couple of different angles which need to be added up to reach the total angle. it's hard to explain. the drawing was specific to a latitude and time of day.
it just bothered me because I have never seen it drawn like that before. even a google search doesn't turn up with a sample of this.
