Highcharts：从地图向下钻取到图表

Question

请考虑Kuwait地图：

我希望当用户单击一个州（例如 - Al Jahrah）时，会出现 Al Jahrah 系列的柱形图。例如：

Category For: Al Jahrah            Value For: Al Jahrah 
--------------------------------------------------------
Cat1                               10
Cat2                               12
Cat3                               3

我通过互联网搜索，但我只看到国家深入到各州。可能吗？

谢谢

您可以创建两个函数来负责创建不同类型的图表并在正确的事件中调用它们：

function mapChart() {
    Highcharts.mapChart('container', {
        chart: {
            map: 'countries/kw/kw-all'
        },

        title: {
            text: 'Highmaps basic demo'
        },

        subtitle: {
            text: 'Source map: <a href="http://code.highcharts.com/mapdata/countries/kw/kw-all.js">Kuwait</a>'
        },

        mapNavigation: {
            enabled: true,
            buttonOptions: {
                verticalAlign: 'bottom'
            }
        },

        colorAxis: {
            min: 0
        },

        series: [{
            data: data,
            name: 'Random data',
            point: {
                events: {
                    click: function() {
                        columnChart(this.name);
                        document.getElementById("back").style.display = "block"
                    }
                }
            },
            states: {
                hover: {
                    color: '#BADA55'
                }
            },
            dataLabels: {
                enabled: true,
                format: '{point.name}'
            }
        }]
    });

    document.getElementById("back").style.display = "none";
}

function columnChart(name) {
    var data = [1, 2, 3];

    if (name === "Al Jahrah") {
        data = [2, 2, 2];
    }

    Highcharts.chart('container', {
        title: {
            text: name
        },
        series: [{
            type: 'column',
            data: data
        }]
    });
}

mapChart();
