I try to calculate the price next to it in a table for my respective daily electricity consumption.
The calculation is very simple and the data value is also available. However, I do not know how I can map this in Grafana.
Can someone tell me how this works?
Attached is a picture, there exemplary values written behind as I imagine it.
Think AFAIK you cannot use the computed values by Grafana , you can calculate that in your query and use it.
IMHO easier if you have a backend API /webservice which does these calculatons.
