Don't shown datalabels

[fuadsadiqov]

Hello, I use donut chart ng2-charts in angular, I want to add datalabels but nothing seen in canvas.
public doughnutChartOptions: ChartConfiguration['options'] = {
plugins: {
legend: {
display: false
},
datalabels: {
display: true,
color: '#000',
align: 'end',
anchor: 'end',
}
},
}
What can I do?
