Amchart4直到Datatime结束才显示，来自parseend事件中的json文件

Question

我正在寻找解决方案以将我的所有数据显示在amcharts4中，我的数据没有准确显示，只是在显示它们之前就被淘汰了，对他们有什么解决办法？

chart.dataSource.url ="/static/json/{{ Post.Datasource|safe }}.json";
chart.dataSource.parser = new am4core.JSONParser();
chart.dataSource.reloadFrequency = 5000;
chart.dateFormatter.inputDateFormat = "i";
  var title = chart.titles.create();
//Funtion Date From and to
chart.dataSource.events.on("parseended", function(ev) {
      var data = ev.target.data;
    for (var i = 0; i < data.length; i++) {
      var startdate = new Date(data[0]["DATETIME"]).toISOString().replace("T"," ").replace("Z","").replace(".000","");
      var enddate = new Date(data[data.length -1]["DATETIME"]).toISOString().replace("T"," ").replace("Z","").replace(".000","");
  }
    title.html = (
        "Data from :" + '<span class="colors"> ' +
        startdate+ '</span> ' +
        " to " + '<span  class="colors">' +
        enddate + '</span>'
    );
});

文本显示的数据不足实际长度，而且我的标题未刷新

时刻库可以轻松转换数据

starttime = moment（starttime）.format（“ YYYY-MM-DD HH：mm：ss”）;
