基于点击的动态高图系列

Question

是否可以使高图显示动态数据库点击按钮？

我有一个资产数组

var assets = [{
    name: "food",
    type: [{
        name: "a",
        y: 129.2
    }, {
        name: "b",
        y: 132
    }]
}, {
    name: "drink",
    type: [{
        name: "drink1",
        y: 512,
    }, {
        name: "drink2",
        y: 412,
    }]
}];

我为highcharts设置了一个空数组，用作系列

var data =[];

然后我设置标题按钮，如每个类别的名称

<button title="food">show food</button>
<button title="drink">show drink</button>

这是我第一次尝试显示动态数据，谢谢。

是的，你可以做，在设置实际数据之前，你需要先串联设置第一个空白数据，然后设置实际数据。

var assets = [{
        name: "food",
        type: [{
            name: "a",
            y: 129.2
        }, {
            name: "b",
            y: 132
        }]
    }, {
        name: "drink",
        type: [{
            name: "drink1",
            y: 512,
        }, {
            name: "drink2",
            y: 412,
        }]
    }],
    colors = ['#76daff', '#b9f', '#99ffa6', '#ffc312'];


$('button').on('click', function() {
    var attr = $(this).attr('title'),
        obj = assets.find(({name}) => name === attr);
        
    chart.series[0].setData([], true);
    chart.series[0].setData(obj.type || [], true);
});

var chart = Highcharts.chart('highchart', {
    chart: {
        type: 'bar',
        backgroundColor: null,
        height: 270,

            formatter: function() {
                return '<div class="myToolTip" style="color:' + colors[this.pos % colors.length] + '">' + this.value + '</div>';
            }
        }

            colorByPoint: true
        }

    tooltip: {},
