Dynamic Tooltip Help

Thanks for Greg_Deckler's concern about this issue. 

Hi, Richard_Clipsto 

I'm not sure I understand what you mean correctly:
By “create a dynamic tooltip which explains how each of these is calculated” do you mean display the DAX formula for each Measure?

If I understand you correctly, you can refer to my method:

As Greg_Deckler said, you need to break a single visual into multiple card visuals.

Then you can fill in the DAX corresponding to the Measure in a new page using Narrative visual:

Then set that page to Tooltip format:

Finally select the corresponding Tooltip page in the Tooltip of the card visual:

I have attached the pbix file for the example below, I hope it helps.

I hope my suggestions give you good ideas, if you have any more questions, please clarify in a follow-up reply.
Best Regards,
Fen Ling,
