I have been finding it difficult to use KPI cards effectively. There are so many types that can be explored to show valuable comparison for month over month or yoy data. I’m a beginner and still learning BI. I understand you have to use DAX to work this out but I’d like to know key step by step process to execute the data. Data set I am currently using is fuel consumption and co2 emission data of aircrafts. Due to sensitivity and confidential data unable to share here. Any tips are well appreciated.

Frankly I haven’t tried yet as I’d like to understand the basic steps for comparison for KPI cards. Something that shows the data vs previous month and year than the KPI data stats alone.
