私の Web サイトに世界地図のグラフを含めようとしています。私の問題は、最初にすべてが機能しているときにページが読み込まれるときですが、ページのビューを切り替えると、マーカーなしで世界地図が読み込まれ、Angular ルーティングで地図を完全に読み込むことができないように見えます。リロードするにはどうすればよいですか?前もって感謝します。

AmCharts.readyは と同等でwindow.onloadあるため、このシナリオではコードが 1 回しか実行されないため役に立ちません。その呼び出しを取り除きready、forEach コードを単独で実行すると、機能します。validateDataまた、プロセスが遅くなるため、各画像が追加された後に呼び出す必要はありません。 forEach が完了した後に一度呼び出すだけです。

前もって画像を作成し、makeChart 呼び出し自体で画像配列に割り当てることができるのに、makeChart の後に forEach コードを実行する理由がよくわかりません。マップの初期化時にのみ画像セットアップ コードを実行する必要がある場合は、マップのinitイベントに配置します。

  var map = AmCharts.makeChart("chartdiv", {
    // ..
    listeners: [
      {
        event: "init",
        method: function(e) {
          var map = e.chart;
          // populate the city dropdown when the page loads
          relevantcities.forEach(function(arrayItem) {
            var city = arrayItem;
            city.svgPath = targetSVG;
            city.zoomLevel = 3;
            city.scale = 1.2;
            city.label = city.title + " +25%";
            city.color = "green";

            // add city object to map
            map.dataProvider.images.push(city);
          });
          map.validateData();
        }
      }
    ]
  });
