Your first image is as close as it can get with plain Chart.js with a single scale, Chart.js does not support scale breaks.

You can add a second Y axis and map the datasets to different scales:

First, this error message is indeed expected on Jan. 11th, 2022.
See "Improving Git protocol security on GitHub".

January 11, 2022 Final brownout.

This is the full brownout period where we’ll temporarily stop accepting the deprecated key and signature types, ciphers, and MACs, and the unencrypted Git protocol.
This will help clients discover any lingering use of older keys or old URLs.

Second, check your package.json dependencies for any git:// URL, as in this example, fixed in this PR.

As noted by Jörg W Mittag:

There was a 4-month warning.
The entire Internet has been moving away from unauthenticated, unencrypted protocols for a decade, it's not like this is a huge surprise.

Personally, I consider it less an "issue" and more "detecting unmaintained dependencies".

Plus, this is still only the brownout period, so the protocol will only be disabled for a short period of time, allowing developers to discover the problem.

The permanent shutdown is not until March 15th.

This is because you are using V2 of chart.js while using V3 syntax. For V2 all x axes scales are in an array calles xAxes and not their own object.

ChartJS : How to display two "y axis" scales on a chart

Asked 2022-Mar-22 at 16:53

I have a chart that shows various data points. Some of these data points are high numbers and some are low numbers.

The low numbers (visits) I can scale to a different scale and this new scale can be put on the "X" axis (It's the "Y" axis and then rotated 90degrees). But the problem is:

The grid remains even when removed

How can I extrapolate the poistion on the graph without adjusting the label data on hover?2 I have search Stackoverflow and ChartJS documentation but can't see how this can be done.

I was trying to use the "other" axis (in this case the top horizontal bar of the chart) so that the scale would be relative and raw data editing would not be needed but I can't get that to work and can't find documentation on this. I'm sure it's possible but I can't see how where.

I have found this question but this related only to ChartJS V2 .

Current version used is ChartJS 3.2.1

You can use a custom label callback for this in the tooltip config, also your scale config was wrong. It was in V2 style. For all changes please read the migration guide

As described in the readme of the zoom plugin you need to use version 0.7.7 if you want to use it together with Chart.js V2. If you want to use the latest version of zoom you will need to update Chart.js to V3 but this has a lot of major breaking changes

For Chart.js 2.6.0 to 2.9.x support, use version 0.7.7 of this plugin.

This is because of your limits you set and the scroll speed. In your limits you told the x to go to max 10 and you made the scroll speed 10 times the default. Setting this to the default and removing the verry aggresive limit on the x axis it works fine:

How to display multiple y axis titles on seperate lines and rotated 90 degrees clockwise in chart.js

Asked 2022-Mar-11 at 14:04

EDIT

My goal is to display several y axis titles on separate lines rotated 90 degrees clockwise in chartjs.

I want the green circled title to be rotated to the orientation of the red circled title while keeping the multi-line title .

The default orientation for multiple titles is the orientation shown in the green circle.

I want the title to be on separate lines (like in the green circle) and rotated 90 degrees clockwise (like the orientation of the red circle).

To get the title on separate lines I essentially create an array of strings like so: Add multiple lines as Y axis title in chartJs

You can add an extra check if it is an array, in which case you first only calculate the padding for the longest element so you dont have a big white space, after that you can calculate the Y starting position and increase it for each element in the array so you can have as many lines as you want

This is because chart.js v3 is treeshakable so you will need to register everyhting you are using. In your case you dont have the pointElement registered. You can do that like this:

Ability to rotate y axis title in chart.js

Asked 2022-Mar-10 at 19:14

I'm trying to rotate the title of the y axis 90 degrees clockwise in chart.js but I couldn't find any way to do this.

This question chartjs: trying to rotate the y-Axis label only rotates the ticks/labels not the y axis title itself.

The only related post I can find is this Ability to rotate axis title and the response was from Jan 26, 2021 saying there was no way to do this.

I have attached my javascript and html code below.

Any help would be greatly appreciated.

The y axis title I would like to rotate is highlighted in red and called: Number of defects. Ideally I'd like to rotate it 90 degrees clockwise.

...

ANSWER

Answered 2022-Mar-07 at 13:57

You can use a custom plugin, to make space you first need to increase the padding on the left, after that you can calculate the correct position by taking the average of the top and bottom y's of the chart area.

Also you should not include chart.js 2 times. When chart.js updates to V4 you will have V4 and V3 installed which will give unwanted behaviour.
