How to calculate difference from 2 dynamic columns in Matrix



I have a matrix where I choose the columns using the slicer. This slicer contains all dates available on my data source.


My goal here is to create a third column where I can calculate the diference of the "coverage" measure. 

Another problem is that I use unpivoted columns, so if I add anoter field to the "value" area, it will insert one more column for each column. 


Any help with this?

Sounds like you are using Field Parameters?


Please provide sanitized sample data that fully covers your issue. If you paste the data into a table in your post or use one of the file services it will be easier to assist you. I cannot use screenshots of your source data.

Please show the expected outcome based on the sample data you provided. Screenshots of the expected outcome are ok.

Hi @lbendlin , thanks for your reply.


The outcome is in the picture below. My wish was to have 2 slicers with single selection (one for the first date and one for the latter), and then check the coverage for both, then the variation: 

The dates available in the slicer would come from the column "datadate" from the sample data. 


Here is the sample data:!Ase08ylVBg_VmVrA2O-wyaVcEWHs?e=MERVOh 

(coverage formula for each column of the sample data is: (1 - (count of N/A in column / count of all column))
coverage variation formula is (last date - first date)


Thank you for the help!

Hi, @ldamato 


The data you provided in the link doesn't quite match the data in your chart. Do you need another conversion?
