javascript - AmCharts 4 donut chart - 自定义 URL 的超链接

Question

我无法获得指向 this 的超链接amcharts4中的 donut chart 。我成功使用 amcharts 3但我没有在 amcharts4 中得到它。

请让我知道我做错了什么。

我还提到了另一个 documentation但无法从中获得帮助。

这是我的脚本:

am4core.ready(function() {

// Themes begin
am4core.useTheme(am4themes_animated);
// Themes end

var chart = am4core.create("chartdiv", am4charts.PieChart3D);
chart.hiddenState.properties.opacity = 0; // this creates initial fade-in

chart.data = [
  {
    country: "India",
    litres: 501.9,
    url:"amcharts.com/docs/v4/tutorials/clickable-links-in-tooltips/"
  },
  {
    country: "Czech Republic",
    litres: 301.9,
    url:"amcharts.com/docs/v4/tutorials/clickable-links-in-tooltips/"
  },
  {
    country: "China",
    litres: 201.1,
    url:"amcharts.com/docs/v4/tutorials/clickable-links-in-tooltips/"
  },
  {
    country: "Germany",
    litres: 165.8,
    url:"amcharts.com/docs/v4/tutorials/clickable-links-in-tooltips/"
  },
  {
    country: "Australia",
    litres: 139.9,
    url:"amcharts.com/docs/v4/tutorials/clickable-links-in-tooltips/"
  },
  {
    country: "Japan",
    litres: 128.3,
    url:"amcharts.com/docs/v4/tutorials/clickable-links-in-tooltips/"
  }
];


chart.innerRadius = am4core.percent(40);
chart.depth = 120;

chart.legend = new am4charts.Legend();

var series = chart.series.push(new am4charts.PieSeries3D());
series.dataFields.value = "litres";
series.dataFields.depthValue = "litres";
series.dataFields.category = "country";
series.slices.template.cornerRadius = 5;
series.colors.step = 3;
series.urlField= "url";
series.urlTarge= "_blank"

}); // end am4core.ready()

这是 HTML 部分:

<div id="chartdiv"></div>

和CSS

<style>
#chartdiv {
  width: 100%;
  height: 500px;
}

</style>

Answer 1

您需要使用 property binding并绑定(bind)Slice的 url property到"url"输入您的数据，例如

series.slices.template.propertyFields.url = "url";
series.slices.template.urlTarget = "_blank";

演示:

如果 "url"存在于数据中，切片将鼠标光标变为悬停指针，单击它将带您到新窗口中的链接。
