Topic on Extension talk:ChapTimeline

I installed Semantic MediaWiki and ChapTimeline today, but couldn't get the latter to work. My #ask query works okay, i.e. it displays data nicely as long as the "format" parameter is not "chap-timeline". If it is, the generated HTML is

<div class="chap-timeline"><div id="chap-timeline-1" class="container"></div></div>

but nothing is displayed there.

I also installed the InteractiveTimeline extension which works flawlessly.

Thanks for consideration!

I had the same problem. Please check if you have two date fields selected first. my query looks like thisː

{{#ask:[[Date2::+]]
|?Date2
|?Date1
|?Project
|?User
|mainlabel=-
|format=chap-timeline
<!-- Parameter for Chap-Timeline -->
|startproperty=Date1
|endproperty=Date2
|height=auto
|zoomable=true
}}
