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:

ChartJS 3 vertical annotations

Asked 2022-Mar-23 at 07:56

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

Answered 2022-Mar-23 at 07:56

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:

We hit a similar problem and needed to make sure we globally register the annotation plugin in our project root.

Without this, the annotation silently fails just as you are describing:

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 plugins.

This is an example that works with the given versions. Please note that I added the annotation object right away in options what gives the wanted annotation. (In my example in form of a red line.)

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.
