The link for your Plugin is broken. You need to remove @2
from the end:
https://cdn.jsdelivr.net/npm/chartjs-plugin-datalabels
There is also the not defined error because you reference ChartDataLabels
which has not been declared. You need to put it in a string:
//DOUGHNUT GRAPH
var doughnutChartData = {
labels: [
'Dr @ Fault',
'TP @ Fault',
'Wthr Evt',
'Other'
],
datasets: [
{
label: "slices",
borderWidth: 3,
data: [2,3,2,1],
backgroundColor: [
'#D6001C',
'#00A3E0',
'#52A886',
'#2E3138'
],
borderColor: [
'#fff',
'#fff',
'#fff',
'#fff'
]
}
]
};
//DOUGHNUT CHART OPTIONS
var doughnutChartOptions = {
responsive: true,
plugins: {
datalabels: {
formatter: function (value, context) {
return context.chart.data.labels[
context.dataIndex
];
},
},
title: {
display: true,
text: "Reported Fault Allocation",
color: "#D6001C",
font: {
family: "AvenirNextLTW01-Regular",
size: 16,
style: 'normal'
}
},
legend: {
display: false
}
},
scales: {
x: {
grid: {
display: false,
drawBorder: true
}
},
y: {
grid: {
display: true,
drawBorder: true,
},
},
},
elements: {
point: {
radius: 0
}
},
}
//DISPLAY DOUGHNUT GRAPH
var ctx = document.getElementById("canvas3-detailed").getContext("2d");
window.myDoughnut = new Chart(ctx, {
plugins: ["ChartDataLabels"],
type: "doughnut",
data: doughnutChartData,
options: doughnutChartOptions
});

I found out that the version of the plugin I used was incorrect. I have now updated and it is displaying with labels!
//DOUGHNUT GRAPH
var doughnutChartData = {
labels: [
'Dr @ Fault',
'TP @ Fault',
'Wthr Evt',
'Other'
],
datasets: [{

'#2E3138'
],
borderColor: [
'#fff',
'#fff',
'#fff',
'#fff'
]
}]
};
//DOUGHNUT CHART OPTIONS
var doughnutChartOptions = {
