我在玩这张图表：

Package 气泡分裂，我想使传说（Asia，Europe等）出现在每个气泡的中心。events可以吗？我试过这样的东西：

Highcharts.chart(chartContainer, {
    chart: {
        type: 'packedbubble',
        renderTo: chartContainer,
        events: {
            render: function() {
                const chart = this;
                chart.series.forEach(function (series) {
                    var data = series.data; // Get all the data points for the series
                    var totalX = 0;
                    var totalY = 0;
                    var totalPoints = data.length;

                    // Calculate the total X and Y coordinates of the data points
                   
                        })
                        .add();
                });
            }
        }
    },

不走运，我不能把它们放在中间。我想知道是否有一种方法可以实现它。
