Chartjs-Angular how to display data inside every part of doughnut chartjs

0👍

This is not possible by default in chart.js so you will need a plugin for this, a great plugin to use is the datalabels plugin

Chart.register(ChartDataLabels);

const options = {
  type: 'doughnut',
  data: {
    labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
    datasets: [{
      label: '# of Votes',
      data: [12, 19, 3, 5, 2, 3],
      backgroundColor: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"]
    }]
  },
  options: {
    plugins: {
      datalabels: {
        formatter: (value, ctx) => (ctx.chart.data.labels[ctx.dataIndex]),
        color: '#fff',
      }
    }
  }
}

const ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);
