% calculation with bar gauge template

Hello,

I designed an interface chart with the bar gauge template in Grafana, but I want to see the mb/s - kb/s values as “%”.

I also want to define a source specific mb/s limit.

Example;
Warehouse A: Calculate % over MAX 100 mb/s.
Warehouse B: Calculate % over MAX 60 mb/s.

Can you help me with this?
