AmCharts 4 删除 MapChart 中的大陆（是）

Question

我正在使用 @amcharts/amcharts4-geodata/worldLow" 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 space 使地图相应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;

Answer 1

在记录的多边形系列中使用 exclude 属性 here

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;
 }
