如何在chartjs中以编程方式触发悬停

<canvas id="myChart"></canvas>

var ctx = document.getElementById('myChart').getContext('2d');
var myChart = new Chart(ctx, {
    type: 'bar',
    data: {
        labels: ['Red', 'Blue', 'Yellow', 'Green', 'Purple', 'Orange'],
        datasets: [{
            label: '# of Votes',
            data: [12, 19, 3, 5, 2, 3],
            backgroundColor: [
                'rgba(255, 99, 132, 0.2)',
                'rgba(54, 162, 235, 0.2)',
                'rgba(255, 206, 86, 0.2)',
                'rgba(75, 192, 192, 0.2)',
                'rgba(153, 102, 255, 0.2)',
                'rgba(255, 159, 64, 0.2)'
            ],
            borderColor: [
                'rgba(255, 99, 132, 1)',
                'rgba(54, 162, 235, 1)',
                'rgba(255, 206, 86, 1)',
                'rgba(75, 192, 192, 1)',
                'rgba(153, 102, 255, 1)',
                'rgba(255, 159, 64, 1)'
            ],
            borderWidth: 1
        }]
    },
    options: {
        responsive: true,
        scales: {
            y: {
                beginAtZero: true
            }
        },
        plugins: {
            tooltip: {
                enabled: false // 禁用默认的悬停效果
            }
        }
    }
});

var activePoints = myChart.getElementsAtEventForMode(event, 'nearest', { intersect: true });

if (activePoints.length > 0) {
    var firstPoint = activePoints[0];
    var label = myChart.data.labels[firstPoint.index];
    var value = myChart.data.datasets[firstPoint.datasetIndex].data[firstPoint.index];
    console.log("悬停在：" + label + "，数值为：" + value);
}
