GANTT CHART - Without Extension - Show gaps between processes


i`ve created a GANTT-Chart without extensions- 


  • Start: min(Start_Date)
  • Duration: Sum(End_Date - Start_Date)

As dimension i`ve used "Plant".

Now i would like to display if and when a plant is occupied or not. It`s not relevant for me which product is produced in that plant. 

As you can see my GANTT-Chart doesn`t show the time-periods where the plant if free between two processes. 

Additionally it sums  up all processes which are in that plant at the same time (Plant: 7 East). But it doesn`t make sense. Do i have to use a "distinct-expression"?

Do i have wrong measures and how can i solve it?


Attached you can find the data and the Chart.


Thank you!

Because of the 14 East factory, this is a dual between the SQL version of Packing Intervals along with Islands-and-Gaps.  Both are kind of obnoxious to solve.

This problem looks easy, but can become pretty involved.
