Question

我正在尝试将网络json文件导入vis.js，并希望所有边缘都以各自的颜色显示。

它适用于节点但不适用于边缘，有没有办法独立于各自的节点显示边缘？任何指导表示赞赏

这是json文件

{ 
  "nodes":
  [
    {
      "id": "1",
      "label": "A",
      "color": "rgb(128,128,128)"
    },
    {
      "id": "2", 
      "label": "B",
      "color": "rgb(0,255,0)"
    },
    {
      "id": "3", 
      "label": "C",
      "color": "rgb(0,0,255)"
    }
  ],
  "edges": 
  [
    {
      "source": "1",
      "target": "2", 
      "id": "1", 
      "color": "rgb(255,0,0)"
    },
    { 
      "source": "1",
      "target": "3",
      "id": "2",
      "color": "rgb(0,0,0)"
     }
  ]
}

这是HTML页面

您的JSON数据结构看起来像vis.js所期望的。可能是您将边缘颜色选项“继承”设置为false吗？在文档示例中，它将网络边缘选项的字段设置为“ from”，如果要调整解析器选项，则将键更改为“ inheritColors”：https://almende.github.io/vis/docs/network/edges.html; https://almende.github.io/vis/docs/network/index.html?keywords=network（控制F代表“ inheritColors”）

从json导入时，vis.js无法更改边缘颜色
