hantongyou opened a new issue, #19665: URL: https://github.com/apache/echarts/issues/19665
### Version 5.4.3 ### Link to Minimal Reproduction https://echarts.apache.org/examples/zh/editor.html?c=tree-vertical ### Steps to Reproduce 1.我使用的是自定义的数据，但是数据格式和官网示例的数据结构保持一致； 2.对于其中每一个数据项我设置了一个属性用以自定义节点边框样式，通过设置如下的itemStyle配置项： ```javascript ... itemStyle: { borderColor: function(params){ if(params.data.value>10) return "red"; else return "green"; } } ... ``` 3.在我尝试失败之后，我试图打印params，但是并没有任何东西被打印，同时如果我直接在borderColor中return "red"也并没有成功修改样式，这是为什么？为了达成自定义样式的效果我应该如何做？ ### Current Behavior 渲染树状图节点时自定义修改节点边框样式失效 ### Expected Behavior 可以根据节点属性值自定义节点边框样式 ### Environment ```markdown - OS:windows 11 - Browser:Chrome 122.0.6261.70 - Framework:[email protected] ``` ### Any additional comments? _No response_ -- This is an automated message from the Apache Git Service.
