Hi, today I released a first version of a Qlik Sense extension called Compare Period Chart.

My ambition is to leverage one of Qlikview/Qlik Sense most powerful features in a more user friendly way, the Set analysis. I want to separate it from the measure as it's own entity, and make it addative. Just like a filter. This is demonstrated in this extension.
Check out the example app included in the extension!

This is just the first version and I want to improve this with the help of the community and the developers from Qlik.
Roadmap
Axis customization
Custom colors
Custom components for better UX
Best regards
Karl
