Chart.defaults.global.tooltips.callbacks.label only works for bar, line

Expected Behavior

Global setting for tooltips for all chart types I would like to use the global settings to set the display of the tooltips without having to do this via the “options”.

Current Behavior

Chart.defaults.global.tooltips.callbacks.label only works for bar, line

Context

Chart.defaults.global.tooltips.callbacks.label = function (	
			tooltipItem,
			data
		) {
			let dataset = data.datasets[tooltipItem.datasetIndex];
			let datasetLabel = dataset.label || ""
			let suffix = dataset.unit || ""
			console.log('Tooltips.label',tooltipItem, data )
			return (
				" " + datasetLabel + ": " + dataset.data[tooltipItem.index].toLocaleString()  + " " + suffix
			);

Environment

• Chart.js version: “chart.js”: “^2.9.4”
• Browser name and version: Chrome Version 86.0.4240.80 (Offizieller Build) (x86_64)

Am I doing something wrong ?

Chart.defaults.doughnut.tooltips.callbacks.label = overrideFunction;

Thanks, now it is working, perfect 👍

You should be able to override the defaults for the other chart types with something like the following. You would need to override it for the 'bubble', 'doughnut', 'pie', 'polarArea', and 'scatter' chart types.

Chart.defaults.doughnut.tooltips.callbacks.label = overrideFunction;
