Highcharts - 如何在区域堆积图表中改变世界地区风格

Question

我正在尝试这张图表：

我如何设计世界区域的样式以便所有区域都出现？在前视图中，它们以直线显示，但最终视图显示在3列中。并非所有视图都显示。 TIA！

//Grafica 1
$(function () {
    Highcharts.chart('grafica1', {
        chart: {
            type: 'area',
        },
        title: {
            text: ' '
        },
        xAxis: {
            categories: ['1350', '1400', '1450', '1500', '1550', '1699', '1750'],
            tickmarkPlacement: 'on',
            title: {
                enabled: false
            }
        },
        yAxis: {
            title: {
                text: 'Percent'
            }
        },
        tooltip: {
            pointFormat: '<span style="color:{series.color}">{series.name}</span>: <b>{point.percentage:.1f}%</b> ({point.y:,.0f} millions)<br/>',
            split: true
        },
