如何在创建仪表后更改highcharts规格上的“label”(valueSuffix)?

类似的东西:

chart.series[0].remove();
chart.addSeries({
    name: 'Speed',
    data: [Math.random() * 200],
    tooltip: {
        valueSuffix: parseInt(Math.random() * 200, 16)
    }
});

是的,可以使用html作为yAxis标题。然后你可以使用jquery或js来改变div内容。

var chart = new Highcharts.Chart({

    chart: {
        renderTo: 'container',
        type: 'gauge',
        plotBackgroundColor: null,
        plotBackgroundImage: null,
        plotBorderWidth: 0,
        plotShadow: false
    },

    title: {
        text: 'Speedometer'
    },

    pane: {
        startAngle: -150,
        endAngle: 150,
        background: [{
            backgroundColor: {
                linearGradient: {
                    x1: 0,
                    y1: 0,
                    x2: 0,
                    y2: 1
                },
                stops: [
                    [0, '#FFF'],
                    [1, '#333']
                ]
            },
            borderWidth: 0,
            outerRadius: '109%'
        }, {
            backgroundColor: {
                linearGradient: {
                    x1: 0,
                    y1: 0,
                    x2: 0,
                    y2: 1
                },
                stops: [
                    [0, '#333'],
                    [1, '#FFF']
                ]
            },
            borderWidth: 1,
            outerRadius: '107%'
        }, {
            // default background
        }, {
            backgroundColor: '#DDD',
            borderWidth: 0,
            outerRadius: '105%',
            innerRadius: '103%'
        }]

    // the value axis
    yAxis: {

        max: 200,

        minorTickInterval: 'auto',

        labels: {
            step: 2,
            rotation: 'auto'
        },
        title: {
            useHTML:true,                text: '<div id="tooltipTitle">km/h</div>'
        },
        plotBands: [{
            from: 0,
            to: 120,
            color: '#55BF3B' // green

        }]
    },

    tooltip: {
        formatter: function(){
        return 'aaa';

    series: [{

// Add some life
function (chart) {
    setInterval(function () {
        chart.series[0].remove();
        chart.addSeries({

            data: [Math.random() * 200]
        });

        $('#tooltipTitle').html('aaaa');
    }, 3000);
});
