DAX Help

[Georgephilip]

I am new to Power BI, struggling with "Measure" - need help in calculating overall satisfaction % which is a sum of rating 4&5 only. Can someone guide/help please?

Also, is there any reference guide to create DAX measures for newbies like me.

Thanks,

George

Hi,

I am not sure how your datamodel looks like, but I tried to create a sample pbix file like below.

Please check the below picture and the attached pbix file.

I hope the below can provide some ideas on how to create a solution for your datamodel.

Satisfaction count: = 
COUNTROWS ( FILTER ( VALUES ( Data[Customer] ), [Rating:] >= 4 ) )

Satisfaction ratio: =
DIVIDE ( [Satisfaction count:], COUNTROWS ( DISTINCT ( Data[Customer] ) ) )
