[Solved]-Highcharts Bubble Chart - How to move an individual point's data label (dataLabel) to the front/top-Highcharts

If you define labelrank as point property, then it will allow you control over label hide/show when labels are overlapping.

    data: [{
        x: 1, y: 1, labelrank: 1, name: 'A'
        },{
        x: 1, y: 1, labelrank: 2, name: 'B' 
        }]
    }]
