amcharts - AmCharts4 删除地图图表中的大陆

Question

我@amcharts/amcharts4-geodata/worldLow"用来创建一个简单的地图，但不需要南极洲。有没有办法隐藏或删除它，但地图利用南极洲留下的空间来使地图相应地调整并使其他大陆更加突出？

初始化代码：

import * as am4maps from "@amcharts/amcharts4/maps";
import am4geodata_worldLow from "@amcharts/amcharts4-geodata/worldLow";
import am4themes_animated from "@amcharts/amcharts4/themes/animated";

let chart = am4core.create("globediv", am4maps.MapChart);

try {
    chart.geodata = am4geodata_worldLow;
} catch (e) {
  chart.raiseCriticalError(new Error("Map geodata could not be loaded."));
}

chart.projection = new am4maps.projections.Projection;
chart.panBehavior = "move";

let polygonSeries = chart.series.push(new am4maps.MapPolygonSeries());
polygonSeries.data = myData;
polygonSeries.useGeodata = true;

使用此处exclude记录的 polygonSeries 中的属性

polygonSeries.exclude = ["AQ"];

let chart = am4core.create("chartdiv", am4maps.MapChart);

try {
  chart.geodata = am4geodata_worldLow;
} catch (e) {
  chart.raiseCriticalError(new Error("Map geodata could not be loaded."));
}

chart.projection = new am4maps.projections.Miller();
chart.panBehavior = "move";

let polygonSeries = chart.series.push(new am4maps.MapPolygonSeries());
polygonSeries.useGeodata = true;
polygonSeries.exclude = ["AQ"];

#chartdiv {
  width: 100%;
  height: 400px;
 }
