Gantt chart with gap using stacked bar chart

[Newbie777]

Hello,

I'd like to create gantt chart with gaps using stacked bar chart.  I'd greatly appreciate it if anyone can share with me qvf file example or formula expression to achieve this visualization.  

Thanks for your help in advance.

and it seems to produce the same visualization as my current stacked bar chart, and the gap part is not visualized.  Am I missing something?  The 2nd extension one did not seem to have the qvf file which I can use.  The problem I am facing is by using min(Start) as the expression, I cannot show the gap in the timeline chart.  Also, the duration is added up to the start even though there is a gap in the periods.  

Thanks a lot for your help.
