关于树视图,是否可以为节点指定特定颜色?

Regarding tree view, is it possible to give a specific color to a node?

作为问题状态,想知道我是否可以在echarts树视图中为单个节点设置颜色。

如果不行,有没有办法解决问题?

例如我想要第 2 层的物理是蓝色,比例是黄色?

当然可以。您可以重新定义您想要的节点视觉方式。一般来说,这个选项可以从数据中设置。请 look at docs where this is explained as detailed as possible. I also made a simple demo 在 jsfiddle 上:

data: [{
        "name": "flare",
        "children": [{
          "name": "analytics",
          itemStyle: {  // <--------- this
            borderColor: 'blue'
          },
          "children": [{
            "name": "cluster",
            "children": [{
                "name": "AgglomerativeCluster",
                "value": 3938,
                itemStyle: { // <--------- this
                  borderColor: 'blue'
                }
              },
              {
                "name": "CommunityStructure",
                "value": 3812,
                itemStyle: {  // <--------- this
                  borderColor: 'yellow'
                }
              },
              {
                "name": "HierarchicalCluster",
                "value": 6714
              },
              {
                "name": "MergeEdge",
                "value": 743
              }
            ]
          }]
        }]
      }]
