Moving annotations on Column Chart with Negative Value Google Chart

Just one minor issue preventing this from working. The annotations in your example have text-anchor="middle", not "start".

Change this

$.each($('text[text-anchor="start"]')

to this

$.each($('text[text-anchor="middle"]')

You can verify the correct values if you run in the console

$('text').each((_, label) => console.log($(label).attr("text-anchor"), $(label).text()));

middle Omega
middle Large
middle Medium
middle Tiny
