[Meera556]

Hi,

I'm replicating a chart from tableau to power bi adn it is uses a calculated field as below

max_count= WINDOW_MAX(count of products/TOTAL(count of products))

Can anyone help me how to create DAX for the above calculated field.

Thanks for your help in advance

Hi, @Meera556 

Thanks for @Ritaf1983 reply. In Tableau, the WINDOW_MAX function is used to find the maximum value in a window or a range of data. To achieve a similar calculation in Power BI, you can use following measure.

CountOfProducts = COUNT(YourTableName[YourProductColumnName]) //Calculate the Count of Products

TotalCountOfProducts = CALCULATE([CountOfProducts], ALL(YourTableName))//Calculate the Total Count of Products

RatioOfProducts = DIVIDE([CountOfProducts], [TotalCountOfProducts])//Calculate the Ratio

MaxRatio = MAXX(ALL(YourTableName), [RatioOfProducts]) //Find the Maximum Ratio
