Question

当点击图表的相关区域时，我需要获得类别名称（年龄> 90天，年龄<90天，年龄<60天，年龄<30天，年龄<14天，年龄<7天）。

例如，当我点击红色区域时，它想要提醒“年龄> 90天”。

这是我的Hi图表代码。

Highcharts.chart('ageContainer', {
chart: {
    type: 'area',
},
colors: ['#39AA59', '#CEAE22', '#3E90BC','#B787E6','#ea780e','#F85858'].reverse(),
title: {
    text: 'Age of queued patches during the last year'
},
xAxis: {
    categories: lastMonthsName,
    tickmarkPlacement: 'on',
    title: {
        enabled: false
    }
},
yAxis: {
    title: {
        text: 'Patch count'
    },
    labels: {
        formatter: function () {
            return this.value;
        }
    }
},
tooltip: {
    split: true,
    valueSuffix: ' patches'
},
plotOptions: {
    area: {
        stacking: 'normal',
        lineColor: '#666666',
        lineWidth: 1,
        marker: {
            lineWidth: 1,
            lineColor: '#666666'
        }
    }
},
series: [{
    name: 'Age > 90 Days',
    data: getData[5]
},{
    name: 'Age < 90 Days',
    data: getData[4]
},{
    name: 'Age < 60 Days',
    data: getData[3]
},{
    name: 'Age < 30 Days',
    data: getData[2]
},{
    name: 'Age < 14 Days',
    data: getData[1]
},{
    name: 'Age < 7 Days',
    data: getData[0]
}]});

查看plotOptions.area.events.click了解详情。另请参阅plotOptions.area.trackByArea。您的帖子不包含实例。使用官方示例来提供解决方案。希望这有帮助
