Hi Vlad, I'm afraid Apache ECharts doesn't have the ability to provide rich interactions as you expected with Gantt charts. Since it doesn't provide Gantt charts by default, you need to implement the interactions by yourself if you are creating a custom series.
I'm sorry that perhaps the answer to all of your questions are No by now. We are working with the next major version of Apache ECharts and we will see if there's anything we can do. For now, I'd suggest using some well featured Gantt charts. Like this Highcharts demo: https://www.highcharts.com/demo/gantt/styled-mode Thanks *Ovilia* On Wed, Oct 23, 2024 at 7:25 AM Vladimir Bednikov < vladimir.bedni...@gmail.com> wrote: > Hi dev team, > > I have been using vis-timeline in a VUE app for a while and want to switch > to Apache ECharts.
