An annotation plugin for Chart.js >= 3.0.0. This plugin needs to be registered. It does not function as inline plugin. For Chart.js 2.4.0 to 2.9.x support, use version 0.5.7 of this plugin. This plugin draws lines, boxes, points, labels, polygons and ellipses on the chart area. Annotations work with line, bar, scatter and bubble charts that use linear, logarithmic, time, or category scales. Annotations will not work on any chart that does not have exactly two axes, including pie, radar, and polar area charts.

I have chartjs v2.9.3 in my Django app and it works great. Now I need to add a box to one of my charts using chartjs-plugin-annotation, and I've followed all the steps, but I can't get it to work. I've used chartjs-plugin-annotation v0.5.7 which is for v2.9.3. I get no errors in the console log. First, scripts with chart.js and plugins:...

This is because you putted the options in the place where they belong in V1 of the annotation plugin and the syntax too. For V0.5.7 the annotation options have to be placed in the root of the options and also all the annotations are an array instead of seperate objects:
I am trying to upgrade my chartjs to v3 and with that the annotations plugin. Tried a few different ways but just cannot seem to get the vertical annotation to show. Tried explicitilty adding xScaleID/yScaleID but I believe that in v3 x/y are the new defaults so would have expected those to be the defaults anyway.
Simplified the whole thing down to this JSFiddle...

First you configured the options in the wrong space, the plugin options have to go inside of the options object. The plugins section what you used is for an array containing inline plugins, secondly you need to include the annotation plugin after chart.js since chart.js needs to be loaded first because the annotation plugin uses some functions from chart.js:

It looks like you are trying to implement the annotations plugin as if you would integrate it to a current chart.js version. E.g. your define your annotations in

It seems to be a bug in the annotation plugin because if you build the current master and use that as a source it works fine.
So you will have to wait until a new version of the lib is released

As stated in the documentation of the annotation plugin you need to use version 0.5.7 if you are using chart.js version 2
Important Note For Chart.js 2.4.0 to 2.9.x support, use version 0.5.7 of this plugin Documentation for v0.5.7 can be found on GitHub.
So you will need to remove the annotation plugin and the install the lower version or update to chart.js version 3

I have created a similar working example without reactjs. This can be useful for you to understand. You can refer the fiddle as well. A limitation that am currently facing is if there is data more than 100 then am getting errors while updating the data, performed slicing of data upto 100 to make it working.
