@types/chart.js missing properties

[greghawk]

Documentation Is:

• Missing or needed
• Confusing
• [ x ] Not Sure?

Please Explain in Detail...

Typescript @types for chart.js does not include all types correctly. For example Chart.scaleService does not contain getScaleConstructor and this causes builds to fail that attempt to use these methods

Your Proposal for Changes

Hydrate the @types entries for chart.js

Example

No example is possible unless you want to see a build error

Chart.scaleService does not exist anymore in V3. According to the migration docs it has been renamed to: Chart.registry.
So maby your code is not up to date with the current state of version 3

Types for Chart.js v2.9.x are maintained at DefinitelyTyped, so the issue should be raised there if you are working with v2.

[greghawk]

It is v2 as that is listed as the newest stable correct? I can raise issue there but I was uncertain where to raise it. At least this group is aware now either way. I had to (cough) cast as any to get it to work when using typescript 3.8+.

[LeeLenaleee]

Yes V2 (2.9.4) is the latest stable build, V3 is still in beta
