AmCharts4 删除地图图表中的大陆

如何解决AmCharts4 删除地图图表中的大陆

我正在使用 @amcharts/amcharts4-geodata/worldLow" 创建一个简单的地图图表，但不需要南极洲。有没有办法隐藏或移除它，但地图利用南极洲留下的空间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;

解决方法

在polygonSeries 中使用exclude 属性，如记录的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;
 }
