First I apologize for my english level, I hope it will be understandable. I searched the community and I think this subject is not covered.
A while back, in my job, i had to show variation between two years ofr differents units. Naturally, i went to use waterfall chart, as the business used to do for it.In a financial vocabulary, we call this "Bridges", because it brings you from a situation to another.
In Excel, it was hard and static, therefor i thank it would be great in QlikView.
First, i thank about offset possibility in bar chart but i rapidly faced a problem. I had to write an expression for each bar in my chart !
But if a new unit is created next year, i would have to you enter the app, and change the graph. It was'nt efficient. Furthermore, it wasn't possible to drill down. I had to find an expression and a vizualisation that require only one expression for multiple dimensions.
Look at the attached file, i hope it can be helpfull for you.
You can find two sheets :
The first one show a classic static waterfall chart.
The second one show a dynamic waterfall chart as you can clic bar to drill down and modify sort order
