Delta waterfall diagram

[Anonymous]

Dear Community,

Is it possible to create an extra column for a delta between two columns (in a waterfall diagram)?

In the following there are two screenshots attached where you can see the current diagram in qlik sense and the original which I have to reconstruct in Qlik Sense.

So my problem is that I am able to calculate the difference between two columns but it is not in the right position (like the delta in the second picture. 

I have never worked with a diagram like that before so I really hope that someone can help me. 

Thank you very much!

Kind regards

Josua
