Javascript Amcharts XY图表不显示引出序号

我的图表没有显示气球，我不明白为什么。我有一个气球显示在y光标上，我可以将其更改为显示x轴的值，但我无法在气球中显示x轴值的气球，无论是在x光标上还是在值线之后

我在这里更新了你的小提琴

您需要做的基本上是引用x或y轴，而不是字段名。您还需要向图表中添加项目符号，以显示引出序号

"graphs": [
    {

        "id": "AmGraph-4",
        "balloonText": "[[x]] (km)",  /*CHANGED THIS LINE*/
        "bullet": "round",            /*ADDED THIS LINE*/
        "bulletSize": 1,              /*ADDED THIS LINE*/
        "title": "graph 4",
        "valueAxis": "Not set",
        "lineColor": "#59C45C",
        "lineThickness": 3,
        "fillAlphas": 0.13,
        "fillColors": "#59C45C",
        "fillToAxis": "ValueAxis-2",
        "xAxis": "Distance (km)",
        "xField": "Distance (km)",
        "yField": "Elevation (m)"
    }
],

不确定是否可以引用实际字段名，但在快速测试中，我至少不能引用。

谢谢。这真的让我很难过。我在这些会议中再也看不到任何东西了……请记住，激活XY图表中的项目符号会减慢整个图表的速度，例如放大时。我正试图找到一种方法来选择性地或在缩放级别显示项目符号，以避免性能受到影响。
