How to do arithmetic operation on a field

Grafana Time Series Panel
1

I have a filed ‘count’. I’m grouping the field with a tag ‘service’ and getting the count with spread(). Now I have 2 values, count-a and count-b. Is there any way of doing division operation like

count-a / count-b

You probably want a data transformation. I’m guessing Add field from calculation, but read through the other transformations and see if any look like what you need.

Thanks Diana, Something similar I was looking at. A reason for me to upgrade grafana to latest. Will test it out.
