Can't get Daisy chaining working. Help.

[Tensdale]

I need to have this fit a normal sized paper, thought I could move Cable 2 and the RGB_led connector down with Daisy chaining bit cant get it working. Can anyone help?

The connections in the code: https://pastebin.com/1Q4bGLM8

I tried daisy chaining like shown below but it didn't change anything. Should I move the connectors down some other way?

• Thank you for sharing your usecase. It seems to be related to #293 and partly also #209. The order of the elements in each connection specify wires to be drawn from left to right in the diagram, so you need to swap the order of the C2 connections to force rgb_led to the left in the diagram. See my second diagram below.
• It seems you have terminated the right end of the C1:10 wire at 3 different connectors, which is normally hard to do in real life with the same physical wire end. I assume you either intend to connect these GND terminals together with short wires to a common junction point (using a ferrule or soldering), or daisy chaining short wires between the same terminals. I suggest you specify in the diagram one of these ways. See my alternatives below.
• Is it really your intention to connect G to Blue and B to Green at the rgb_led connector? Their names indicate rather these two connections should be swapped.
• First, I show how a ferrule can be used to avoid terminating the same wire at several connectors:

• Then I show how to daisy chain for a more compact diagram:

tweak:
  override:
    graph:
      ranksep: "4"  # Increase horizontal spacing (default 2) for better readability

• With default horizontal spacing, the wires drawn between C1 and led_driver became hard to separate in this last diagram, so I doubled the horizontal spacing for better readability.
