我有一个带有两列的wireshark提取(TSV) - “日期”和“窗口”,如
date window
31:35.6 524288
31:35.6 524288
31:35.6 524288
31:35.6 524288
31:35.6 522024
31:35.6
31:35.6 521452
...
我想创建一个“窗口”的时间序列图,并使用简单的折线图(mbostock 的块 #3883245)开始。我的 index.html 仅对示例进行了少量编辑,并导致出现错误消息
[19:12:43.516] 类型错误:e 未定义@file:///home/tim/Desktop/test/multiline-2/_attachments/d3.v3.min.js:2
我一定是错过了什么——你能帮忙吗?
