Chart.defaults.plugins.tooltip.callbacks.label global definition is possible?

[lucapollani]

Here is an example:
https://codesandbox.io/s/pensive-mahavira-mknsq?file=/index.html

Is it possible to do something like this to apply to any tooltip?

Chart.defaults.plugins.tooltip.callbacks.label = (context) => {
    console.log(context);
    return `test ${context.label}: ${context.parsed}`;
 };

Pie charts override the normal default for the tooltip thats why its not working, if you change it to a line chart for example it works fine: https://jsfiddle.net/Leelenaleee/c5npL7b1/3/

Got it, so is it an acceptable thing to "override" the overrides?

Something like:

Chart.overrides.pie.plugins.tooltip.callbacks.label = (context) => {
    console.log(context);
    return `test ${context.label}: ${context.parsed}`;
 };

[LeeLenaleee]

Yes

[lucapollani]

Last question... I've found somewhere, don't remember where, this piece of code:

Chart.defaults.override('pie.plugins.tooltip.callbacks', {
	label: context => {
		console.log(context);
		return `test ${context.label}: ${context.parsed}`;
	}
});

Chart.overrides.pie.plugins.tooltip.callbacks.label = (context) => {
    console.log(context);
    return `test ${context.label}: ${context.parsed}`;
 };

Do you know if there's any difference between this two methods or if one is preferable over the other?
I can't find documentation for the first method but it seems to work the same.

If they both work it works, not familliar with the first one but in my oppinion second one is better readable so easyier to maintain

Ok, I'll use it then, thank you very much for the support!
