Highcharts official support forum

Hello everyone,

is it possible to create a gantt chart with the collapsible parent-child structure of the treegrid axis type but with multiple columns like the category type?

I had no luck with my attempts so far, am I right to assume that this is not supported/intended? If yes does anyone have an idea for a workaround to create this kind of chart?

Thanks for your help in advance

Hi,

Welcome to our forum and thanks for contacting us with your question.

I am not sure if I understood you well. You want to create a collapsible structure but with more categories? I can't imagine how should it work. Do you have any draw or online example of it?

Best regards!

Hi,

thanks for the quick reply. Basically I am trying to create something like this

Hello, any progress on this? I want extra columns with treegrid type.

Hi,

Thanks for contacting us with your question.

Unfortunately, it is not possible to achieve that with the "treegrid" type axis. For now, it is working just with the "category" type.

Hello, I am implementing the same feature, I would like to ask how you implemented it

Hi LIAOYU!
Welcome to our forum and thanks for contacting us with your question!

As my colleagues said, sadly, this feature is not supported in Highcharts Gantt yet. You can find the related GitHub ticket here: https://github.com/highcharts/highcharts/issues/13618 It is marked as Feature Request, so feel free to leave some reactions, that you also would like to see this feature implemented.

Feel free to ask any further questions.
Regards!

My team is also trying to implement something similar. Having this enhancement available is critical. You mention this was tagged a Feature Request. Do you have any estimate on how long this will take to reach the final repo? Is there any type of roadmap for it?

Hello,
This feature is still not supported, right?

Thanks, Paulo Torres

Hi!

This feature has been implemented recently and is now available on the master branch of Highcharts. In the next release, it will be added to the Highcharts CDN, but for now you can use it by accessing the commit, like shown in this example: https://jsfiddle.net/BlackLabel/t4Lxv1sz/.
