Telerik 圆环图 - 自定义标签

Question

我想自定义 Telerik 圆环图的标签位置，它应该看起来像预期的图像。我尝试了几个设置，但无法调整标签位置，请参见 poc 图片。

问题 - 如何更改标签位置，使其看起来像预期的图像。我想要 5,10,15,20,25, ... 在第二个环之外，标签应该在每个类别的末尾。

代码

$("#chart").kendoChart({
  legend: {
    visible: false
  },
  chartArea: {
    background: ""
  },
  seriesDefaults: {
    type: "donut",
    startAngle: 90,
    labels:{
      template: "#= category #",
    }
  },
  series: [{
    name: "abc",
    size:50,
    margin:2,
    data: [{
      category: "abc1",
      value: 50,
      color: "#7FBA00"
    },{
      category: "abc2",
      value: 20,
      color: "#007233"
    },{
      category: "abc3",
      value: 30,
      color: "#D2D2D2"
    }]
  }, {
    name: "xyz",
    size:10,
    data: [{
      category: "5",
      value: 10,
      color: "#ccc"
    },{
      category: "10",

我不知道有任何选项可以设置您想要的特定位置，但无论如何您都可以欺骗 Telerik 这样做。关键是 将标签放在没有背景颜色的第三个外部甜甜圈中 并排列切片的值，使它们与现在不再需要标签的第二个（交替灰色）甜甜圈相匹配.

$("#chart").kendoChart({
  legend: {
    visible: false
  },
  chartArea: {
    background: ""
  },
  seriesDefaults: {
    type: "donut",
    startAngle: 90,
    labels:{
      template: "#= category #",
    }
  },
  series: [{
    name: "yourData",
    size:50,
    margin:2,
    data: [{
      category: "abc1",
      value: 50,
      color: "#7FBA00"
    },{
      category: "abc2",
      value: 20,
      color: "#007233"
    },{
      category: "abc3",
      value: 30,
      color: "#D2D2D2"
    }]
  }, {
    name: "grayAxis",
    size:10,
    data: [{
      value: 10,
      color: "#ccc"
    },{
      value: 10,
      color: "#AFAFAF"
    },{
      value: 10,
      color: "#ccc"
    },{
      value: 10,
      color: "#AFAFAF"
    },{
      value: 10,
      color: "#ccc"
    },{
      value: 10,
      color: "#AFAFAF"
    }]
  } , {
    name: "numbers",
    size:10,
    data: [{
      category: "",
      value: 9,
      color: "none"
    },{
      category: "5",
      value: 1,
      color: "none"
    },{
      category: "",
      value: 9,
      color: "none"
    },{
      category: "10",
      value: 1,
      color: "none"
    },{
      category: "",
      value: 9,
      color: "none"
    },{
      category: "15",
      value: 1,
      color: "none"
    },{
      category: "",
      value: 9,
      color: "none"
    },{
      category: "20",
      value: 1,
      color: "none"
    },{
      category: "",
      value: 9,
      color: "none"
    },{
      category: "25",
      value: 1,
      color: "none"
    },{
      category: "",
      value: 9,
      color: "none"
    },{
      category: "X",
      value: 1,
      color: "none"
    }],
    labels: {
      visible: true,
      background: "transparent",
      template: "#= category #",
      position: "center"
    } 
  }]
});

现在，您当然可以将 "X" 替换为 "" 以获得空的顶部标签，您可以调整第三个甜甜圈的值，使其更整齐，您可以将原点从90 度，例如89.5 度，您可以使用我在第三个甜甜圈和第二个甜甜圈中使用的相同 9+1 方案来获得 gray-with-tiny-white-separators 布局等

无论哪种方式，这就是我要走的路：让你的第二个甜甜圈看起来像你想要的那样，并使用基本上不可见的第三个甜甜圈来放置你的轴标签。

很漂亮，不是吗？
