我正试图建立一个chart.js线和散点，我想有数据标签显示只是在散点，我已经尝试过用datalabels插件从图表js，但它显示了所有数据集的数据标签，包括线，我怎么能只显示特定的散点？这是代码看起来像什么：

Chart.register(ChartDataLabels);
        fetch('https://raw.githubusercontent.com/ConeDigital/assets/main/data.json')
        .then(response => response.json())
        .then(data => {
            var ctx = document.getElementById('myChart2').getContext('2d'),
                chart = new Chart(ctx, {
                    type: 'line',
                    data: getChartData(data),
                    options: {
                        legend: {
                            display: false
                        },
                         plugins: {
                                datalabels: { // This code is used to display data values
                                    anchor: 'end',
                                    align: 'top',

                                    }
                                }

                                },

现在它显示了所有数据集的所有数据标签，看起来很混乱，提前感谢
