[Solved]-Highcharts gauge property-Highcharts

this is a datalabel.

data labels for the gauge. for gauges, the data labels are enabled by default and shown in a bordered box below the point.

you can change it in the plotoptions config or the series config as i've done in this example.

    series: [{
        name: 'speed',
        data: [80],
        tooltip: {
            valuesuffix: ' km/h'
        },
        datalabels:{enabled:false} // <-- turn that off
    }]
