How to display calculation logic in a Single Value Panel on Hover or Click ?

[Muthu_Vinith]

Hi Experts, 

I have a question regarding our Splunk Dashboard. I want to show the logic of the calculation used in a single value panel. Specifically, I would like to display this information when a user hovers over the panel or clicks a question mark (?) or information (i) symbol. 

Is it possible to add this feature to a particular single value panel? Any guidance or examples would be greatly appreciated.

Thank you
