如何修改树图中节点的属性?

How to modify the attributes of nodes in a treemap?

我构建了一个树状图并想改变图形的一些属性,即节点描述中使用的字体大小并指定各种节点的颜色

当右键单击图表并选择 "View Source" -> "Parsed JSON" 时,我看到设置已放在 labels 的每个元素中。我如何在渲染之前访问这些以强制我的选择(全局(字体)或每个节点(背景颜色))?

由于解析的 JSON 视图显示,作为示例,对于 label 的给定元素,"background-color":"#1f1f1f" 设置为与 text 相同的级别,我试着把这个放在我的 series:

{
  "text": "Candidates",
  "children": [
    {
      "text": "Can not scan: 13 %",
      "value": 13
    },
    {
      "text": "Scanned: 87 %",
      "children": [
        {
          "text": "Not authenticated: 61 %",
          "children": [
            {
              "text": "Confirmed vulnerable: 38 %",
              "value": 38,
              "font-color": "yellow"
            },
            {
              "text": "Unknown: 23 %",
              "value": 23
            }
          ]
        },
        (...)

但未应用 "font-color": "yellow"(或任何其他属性)。

在我们的树状图文档页面 first example 上,我们有一个调色板示例来说明如何更改颜色。该代码如下所示:

 var myConfig = {
  "type":"treemap",
  "options":{
      "split-type":"balanced",
      "color-type":"palette",
      "palette":["#f44336","#29b6f6","#ab47bc","#ffc107","#5c6bc0","#009688"]
  },
  "plotarea":{
    "margin": "0 0 35 0"
  },
  "series":[
      {
          "text":"North America",
          "children":[
...

如果要更改 options.box 内完成的字体大小:

var myConfig = {
  "type":"treemap",
  "options":{
      "split-type":"balanced",
      "color-type":"palette",
      "palette":["#f44336","#29b6f6","#ab47bc","#ffc107","#5c6bc0","#009688"],
      box: {
        fontSize:15
      }
  },
  "plotarea":{
    "margin": "0 0 35 0"
  },
  "series":[
      {
          "text":"North America",
...
