How to change name of tooltip label for cpu core temp?

I’m using grafana in a docker container on Unraid linux. I want to monitor my router and have a prometheus exporter which is working fine and connected to grafana. I’m creating my first panel and want to monitor CPU Core temperatures.

It’s working fine, but I want to change the label in the tooltips from

{name=“node_cpu_temperature_celsius”, cpu=“1”, instance=“router.localdomain:9100”, job=“prometheus”}

to Core 1

How do I do that? Tried all kinds of things without success. Here’s my panel so far

It sounds like you want to display the field as something simpler? Did you try any of the transformations? There are many possible transformations, but the Organize Fields transformaiton is perhaps the easiest.
