Naming a field with Grafana 9 and Influxv2

I have 2 queries (A and B).
A has
|> filter(fn:(r) => r[“_field”]==“bytes_recv” )

B has
|> filter(fn:(r) => r[“_field”]==“bytes_sent” )

I am not sure how to show this on the graph when I hover over it.

Like this?

yes. exactly. how did you do that?

Can you share a screenshot of your query and the time series visualization? (ideally with your mouse over the graph where you believe a tooltip text should appear when you hover over it)
