- What Grafana version and what operating system are you using? I am using v9.5.5 - **What** are you trying to achieve? When applying Labels to fields transformation, the legend will be by default the combination of the labels that I have selected, I want to change this to only specific labels (only node and time in this case). You can see the default behavior in this image: **Note** : I know that not all legend have pipeline\_id, that is because I added this label recently, just focus on the 4th line where all labels exist. - **How** are you trying to achieve it? Apply rename by regex transformation after the “Labels to fields” transformation - What happened? When I add the "Rename by regex, it surprisingly set the legend to “Value” and matches to it as shown in the picture: - What did you **expect** to happen? I expected to match to the combination of labels that was previously Some of you might suggest using value mappings, but I can’t use it in this case because right now I have a data link that reads the value of one of the labels (pipeline\_id in this case), and when I use value mappings to remove the pipeline\_id, it actually removes it also from the link. “Rename by regex” doesn’t have this effect, since I tried it in different graphs (where I did not use “Labels to fields” obviously)
