我的数据在d3.js数据中未定义

我正在尝试构建一个折线图,当用户将鼠标悬停在图表的一部分上时,会出现带有日期,国家和事件数据点的标注。但是目前我所有的数据点都显示为“未定义”。有人知道这是怎么回事吗?

这是我的代码。

function circleHover(chosen) {

  if (modus == "incidents") {

    d3.select("#callOut")
      .style("top", "570px")
      .style("left", "30px"); 


    d3.select("#divCountry").html('Country: ' + chosen.country);
    d3.select("#divDate").html('Date: ' + chosen.date);
    d3.select("#divIncidents").html('Incidents: ' + chosen.incidents);

    d3.select("#callOut")
    .style("visibility","visible");

  }

  if (modus == "fatalities") {

    d3.select("#callOut2")
      .style("top", "570px")
      .style("left", "30px");  

    d3.select("#divCountry2").html('Country: ' + chosen.country);
    d3.select("#divDate2").html('Date: ' + chosen.date);
    d3.select("#divFatalities2").html('Fatalities: ' + chosen.fatalities);

    d3.select("#callOut2")
    .style("visibility","visible");

  }

  if (modus == "injuries") {

    d3.select("#callOut3")
      .style("top", "570px")
      .style("left", "30px"); 

    d3.select("#divCountry3").html('Country: ' + chosen.country);
    d3.select("#divDate3").html('Date: ' + chosen.date);
    d3.select("#divInjuries3").html('Injuries: ' + chosen.injuries);

    d3.select("#callOut3")
    .style("visibility","visible");

  }

};
