ChartJS show value in legend (Chart.js V3.5)-CodePudding

I need the value of chart show after name of data for example ([colour of data] Car 50, [colour of data] Motorcycle 200). I've tried change the value of legend title but it doesn't work at all

Here is it my code

var ctx = document.getElementById('top-five').getContext('2d');
            var myChartpie = new Chart(ctx, {
                type: 'pie',
                data: {
                    labels: {!! $top->pluck('name') !!},
                    datasets: [{
                        label: 'Statistics',
                        data: {!! $top->pluck('m_count') !!},
                        backgroundColor: {!! $top->pluck('colour') !!},
                        borderColor: {!! $top->pluck('colour') !!},
                    }]
                },
                options: {
                    plugins:{
                        legend:{
                            display:true,
                            title:{
                                text: function(context) {//I've tried to override this but doesn't work
                                    var value = context.dataset.data[context.dataIndex];
                                    var label = context.label[context.dataIndex];
                                    return label ' ' value;
                                },
                            }
                        },
                    },
                    responsive: true,
                }
            });

You can use a custom generateLabels function for this:

var 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: {
      legend: {
        labels: {
          generateLabels: (chart) => {
            const datasets = chart.data.datasets;
            return datasets[0].data.map((data, i) => ({
              text: `${chart.data.labels[i]} ${data}`,
              fillStyle: datasets[0].backgroundColor[i],
            }))
          }
        }
      }
    }
  }
}

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