Node/Edge ordering issue

[alirussell]

Im having an issue with keeping a consistent ordering of nodes/edges in my graph. The images below show how an extra node in the graph seems to completely change the ordering.

I am making sure that i use the same order for edges and nodes in each render, and I'm checking the init-order method and it seems to be ranking them in the correct order there, but somewhere it seems to be changing and i can't figure out why. i have checked out a few of the discussions about clustering and other order related issues, but can't see any solution.

I also didn't seem to get this with an older version, but i can't remember which version it was.

Any help would be much appreciated

Hey @alirussell

its been 3 years :/

did you manage to resolve this?

4 years, something new?

something new?

Disabling the optimal order heuristics fixes this. To do that, fork the repo and add a return; here.
Alternatively just import from a forked repo where this is already fixed, like mine traverse-dagre (however this is used for my own project Traverse, so use at your own risk)

Any chance of getting it fixed?

I have just solved this problem by a simple way via skipping the Post-conditions of ordering process.

More specifically, I only add return; line for node_moduels/dagre/lib/order/index.js L36.

• Lock the version = 0.8.5

"dagre": "0.8.5"

• Install patch-package

npm i -D patch-package

• Create postinstall npm script

{
  "script": {
    "postinstall": "patch-package"
  }
}

• Create directory for patches and the specific path file

mkdir patches
touch patches/dagre+0.8.5.patch

• Edit dagre+0.8.5.patch with the following content

diff --git a/node_modules/dagre/lib/order/index.js b/node_modules/dagre/lib/order/index.js
index 4ac2d9f..6db0b92 100644

• Run npm install
