【问题标题】：Does Vis Timeline tooltips work timeline - groups-ordering?Vis 时间线工具提示是否工作时间线 - 组排序？

【问题描述】：

我正在尝试让工具提示与时间轴一起使用 |团体订购。我收到了错误：

未捕获的错误：未提供容器在 Timeline.Core._create (vis.js:9748) 在新的时间线 (vis.js:40685)

有没有时间线的例子 |使用工具提示进行分组排序？

【问题讨论】：

似乎 tooltips-follow 不支持带有选项的组！我现在得到一个包含组但没有工具提示的时间线和一个没有组和工具提示的单独时间线。

标签： vis.js vis.js-timeline

【解决方案1】：

所以它只通过添加标题标签就可以工作，而使用跟随选项是行不通的。谢谢
