Hello Bruno, thanks for reaching out to us. I would appreciate if you could answer following questions to understand better.
1. What is the main decision or insight you want the end user to get from this chart?
2. What are the source fields for the “#” and “€” metrics?
3. Are these metrics calculated from the same dataset, or do they come from different tables/facts?
4. Is there any existing formatting on these metrics (number format, currency format)?
5. Can you share an existing insight/dashboard where this should be added?
Thank you for your cooperation.
