使用drilledDown的HighMaps

Question

我在启用了钻取的应用程序中使用了高位图，它适用于为美国提供的样本数据。

但它不适用于斯里兰卡的数据。可能是什么问题？

这是我的代码：

  $('#container').highcharts('Map', {
        chart : {
            events: {
                drilldown: function (e) {

                    if (!e.seriesOptions) {
                        var chart = this,
                            mapKey = 'countries/lk/' + e.point.drilldown + '-all',
                            // Handle error, the timeout is cleared on success
                            fail = setTimeout(function () {
                                if (!Highcharts.maps[mapKey]) {
                                    chart.showLoading('<i class="icon-frown"></i> Failed loading ' + e.point.name);

                                    fail = setTimeout(function () {
                                        chart.hideLoading();
                                    }, 1000);
                                }
                            }, 3000);

                        // Show the spinner
                        chart.showLoading('<i class="icon-spinner icon-spin icon-3x"></i>'); // Font Awesome spinner

                        // Load the drilldown map
                        $.getScript('https://code.highcharts.com/mapdata/' + mapKey + '.js', function () {

                            data = Highcharts.geojson(Highcharts.maps[mapKey]);

                            // Set a non-random bogus value
                            $.each(data, function (i) {
                                this.value = i;
                                  console.log(i);
                            });


                            // Hide loading and add series
                            chart.hideLoading();
                            clearTimeout(fail);
                            chart.addSeriesAsDrilldown(e.point, {
                                name: e.point.name,
                                data: data,
                                dataLabels: {
                                    enabled: true,
                                    format: '{point.name}'
                                }
                            });
                        });
                    }


                    this.setTitle(null, { text: e.point.name });
                },
                drillup: function () {
                    this.setTitle(null, { text: 'Sri Lanka' });
                }
            }
        }
