ticks.callback first argument contains index instead of value with Chart.js 3

[ankane]

Expected Behavior

The first argument contains the value (like in Chart.js 2 and the docs)

Current Behavior

The first argument contains the index (as well as the 2nd)

Steps to Reproduce

https://codepen.io/ankane/pen/jOywNez

I tried to see if the value was moved to a different argument, but didn't see it any of the other args.

Context

Ran into this trying to upgrade Chartkick to Chart.js 3

Environment

• Chart.js version: 3.0.2
• Browser name and version: Firefox 87.0

My bad, just saw the note about getLabelForValue added in #8798.

This should also be mentioned in the 2->3 migration guide, IMHO.

@mackuba "ticks.callback first argument contains index instead of value with Chart.js 3", Do you fix ?

[chiendang1709]

@mackuba"ticks.callback đối số đầu tiên chứa chỉ mục thay vì giá trị với Chart.js 3", Bạn có khắc phục được không?
