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？任何指导都值得赞赏
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

</html>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，它将网络的边缘选项的此字段设置为"from"，或者如果要调整解析器选项，请将键更改为"inheritColors"：https://almende.github.io/vis/docs/network/edges.html;https://almende.github.io/vis/docs/network/index.html?keywords=network(控件 F 表示"继承颜色"(
