Gantt Chart using Extension Objetcs

Mon, 26 Jan 2026 16:26:21 GMT

Hi Folks,

We have the installed Extension objects and we got some extension objects in the extension folder. We are trying to use Gantt Chart extension object. But this Gantt chart not meet the requirements. I need to prepare the Gantt chart with following requirements:

- bar is based on Dueearly, Duestart, Dueend, and Duelate date

- The colors are based on the due or overdue (if due then blue, over due then red, on schedule then green)

- The Y axis should have tool name, PM Number, Title

- X-axis should have dates

- The GANTT bar itself should show remaining hours, or meter

Please give some suggestions how to achive this. I am new to extension objects.

Thanks in Advance ........

Regards,

Siri

Hi Siri,

If it's not a major requirement that you use extensionobjects, you can just as well use a solution based on a barchart.

Hi Siri

I have been working on a dedicated QlikView Gantt Chart extension object that also shows the task tree and lets the user expand & contract the tree. This is 100% javascript so it can be customised as necessary. I have just posted a preliminary version of it here for feedback http://community.qlik.com/docs/DOC-3427

It is working well with the sample data I built. However I would be keen for others to try it and provide feedback through community (as comments attached through the link provided) so I can resolve any bugs and add functionality that people actually want.
