Need to Convert Complex DAX into New visual calculation

Hi NandhiniNarasi  ,
Thanks for reaching out to the Microsoft fabric community forum.

First select any visual of your choice from visual pane

then Visual calculation will be available to use after selecting any visual of your choice ( not all visuals are supported for visual calculation)

Using Custom visual calculation you can run any DAX of your choice.

Please check this article to know more about visual calculation
Using visual calculations in Power BI Desktop - Power BI | Microsoft Learn
This will help you in converting DAX measures to Visual calculation

Also make a note that  visual calculations work within the confines of the visual matrix, functions that rely on model relationships such as USERELATIONSHIP, RELATED or RELATEDTABLE aren't available.
