how to access data from visualization extension without dimensions

[KohSamui]

I need to build visualization extension that needs to access the list of all dimensions (table fields) in data model and list them to user to select.

Idea is to match certain names in data model and then user selects 1-3 of those and then visualization extension sets correct dimensions and gets the data.

I would like to have empty definition and empty initialProperties and set all according to user selection inside extension view. Is this possible and what API to use and how?

Hi @KohSamui I think this extension is doing what you asked. Please have a look https://developer.qlik.com/garden/5bd1f3373e4dd400115204b0 .

About the API, you have to use both Extension and Engine API.
