Power BI is celebrating its 10th anniversary! To mark this milestone, I invite you to participate in the Power BI Christmas and holiday season Calendar. This special event features 24 unique challenges, each designed for you to solve and enjoy throughout the season.
A new challenge will be released every day, starting December 1st and continuing through December 24th. Each day presents a fresh opportunity to test your Power BI skills and creativity.
At the conclusion of the event, a winner will be selected from among the participants. Microsoft Finland has generously offered a prize, with further details to be provided soon.
Throughout December, we will maintain and announce a leaderboard, showcasing participants’ progress. Correct answers will also be shared. You will have two days to solve each puzzle; for example, the puzzle released on day one will close at the end of day two.
Day 10 Challenge
Today we continue on report visualization problems! Business users want to have a single visual that shows sales and taxes either by Product color or by CurrencyName. Having 2 matrix visuals on the screen takes too much space and this has to be completed with single visual.
Answer how you solved this merging. There are probably multiple different solutions but let’s try to achieve this with 1 matrix visual.
Please describe your solution in a answer form.

This Holiday season / Christmas challenge is provided by Vesa Tikkanen and is not linked to Microsoft as company. I just want us to have a puzzle every day going towards the 24th of December. This is pure community effort without any business relations behind. As such I try to do this as professional as possible but please remind that this is just for us to have fun. Microsoft finland has promised some swag as a prize but they are not related to winner pickup process neither they get any details of attendance. Information regarding attendance is not being used in any other thing than picking up the winner. So no marketing, no contacting just Power BI puzzle every day.
