How to apply dax as measure on specific visual using javascriptapi?

Hi jaryszek ,
Thank you for posting in the Microsoft Fabric Community.

 

Currently, the Power BI JavaScript API does not support dynamically creating or applying new DAX measures to existing visuals within an embedded report. However, you can assign pre-defined measures to visuals using the API's setDataFields() method. For executing custom DAX queries, consider using the Execute Queries REST API, which allows running DAX queries against a dataset and retrieving results.

Please refer to the following documentation for more information:

Datasets - Execute Queries - REST API (Power BI Power BI REST APIs) | Microsoft Learn

For dynamic measure selection, it's advisable to predefine multiple measures in your dataset and enable users to choose among them as needed.
