如何在Highcharts中删除仪表图的边距？

Highcharts.chart('container', {
    chart: {
        type: 'gauge'
    },
    title: {
        text: 'Gauge Chart with No Margins'
    },
    pane: {
        startAngle: -150,
        endAngle: 150,
        background: {
            backgroundColor: Highcharts.defaultOptions.legend.backgroundColor || '#EEE',
            borderWidth: 0,
            borderRadius: 0
        }
    },
    yAxis: {
        min: 0,
        max: 200,
        stops: [
            [0.1, '#55BF3B'],
            [0.5, '#DDDF0D'],
            [0.9, '#DF5353']
        ],
        lineWidth: 0,
        tickWidth: 0,
        labels: {
            y: 16
        },
        title: {
            text: 'Speed'
        }
    },
    series: [{
        name: 'Speed',
        data: [80],
        tooltip: {
            valueSuffix: ' km/h'
        }
    }]
});
