Hello there!
Here is my Math (?) problem:
I am trying to join two points with a line - sounds easy, however I am not really able to find a solution I could be 100% satisfied right now.
Before I tried ;), I was sure, it must work with the Pythagoras’s theorem and a Sinusoid function.
To be sure, that the theory is working at different angles I prepared two simple moving points connected with the dynamic changed tag #BLN# up and down:
Than, I feeded the system with expressions:
Point A (Green left)
Y: (260-((100-#BLN#)*1.6))
Point B (Green right)
Y: (260-((#BLN#)*1.6))
LINE (Black)
Y: (260-((100-#BLN#)*1.6))
(Simple Pythagoras’s theorem – „60” is the horizontal distance and it does not change)
Width: (sqrt((60*60)+((((100-#BLN#)*1.6)-(#BLN#1.6))(((100-#BLN#)*1.6)-(#BLN#*1.6)))))
&
Rotation: (deg(2sin(((100-#BLN#)-#BLN#)/(sqrt((6060)+((((100-#BLN#)*1.6)-(#BLN#1.6))(((100-#BLN#)*1.6)-(#BLN#*1.6))))))))
Just for a better orientation, here is the same with color brackets as an image:
And the result:
As you see, the dynamic changed width (Black Line) seems to be OK, but the angle (Rotation) is just flying around the B point (green point at right). The goal is to prepare a forecast line diagram (I found yesterday only one such a watchface at facer.io*).
My final question: Where did I make a mistake?
I am sorry I could not find this watchface right now (I am not on my computer). However this design shows two lines for low and high temprature for the next app. 5 days. What I remember more is, that the creator war a premium designer*.
**UPDATE (Dec 27, 2017): Here is the watch face from @eradicator09 (tr0n09) in real I was talking about:
