Migration: Check if the label on dataset level is needed

[SeppPenner]

Migrated from Joelius300/ChartJSBlazor#46:

From Joelius300/ChartJSBlazor#40 (comment):

We need to investigate whether the label on dataset basis is valid for all kind of charts.

For pie and doughnut, it has no effect: https://jsfiddle.net/g1anoety/ without the datalabels plugin enabled. (I would remove this for all charts where it's not yet needed and add it again if it's needed after we managed to get Joelius300/ChartJSBlazor#34 done).

Following https://www.chartjs.org/docs/latest/charts/:

• line: Needed, check https://jsfiddle.net/ukwsn6c2/.
• bar: Needed, check https://jsfiddle.net/ukwsn6c2/1/.
• radar: Needed, check https://jsfiddle.net/ukwsn6c2/2/.
• doughnut and pie: Not needed, check https://jsfiddle.net/g1anoety/.
• polar area: Not needed, check https://jsfiddle.net/ukwsn6c2/3/. (We need to remove this!)
• bubble: Needed, check https://jsfiddle.net/ukwsn6c2/4/.
• scatter: Needed, check https://jsfiddle.net/ukwsn6c2/5/.

I have asked the guys from Chart.Js to check this as well and tell us, what's the idea behind this: chartjs/Chart.js#6452.

Thanks for the investigation. This will be respected in #96.

Please see chartjs/Chart.js#6452 (comment). I guess, this is deprecated now? That's how I understood it at least.

[Joelius300]

I was actually quite confused by what happened in that issue. How come it's about title now? I thought this is only about the dataset label which isn't deprecated right?

[SeppPenner]

You're right. I will ask them again.

[Joelius300]

You don't have to.

I'm pretty sure about the labels now, your investigation already helped enough. I think they just misinterpreted the issue you posted. We should just move on, IMO it's all good.

[SeppPenner]

Ok :)

[Joelius300]

I see you already posted something, I guess it won't hurt 😅 but from my side, I don't think it's necessary anymore.
