Replace value of one column using transformation

I am using Prometheus data source for Grafana Dashboard. I have 2 columns (Value and count(count)) as shown below. I need to replace Value column all rows ( condition: value == 3, replace with 'Not a Finding). It does work using Value mapping, but it replaces row 1 and 4 of Value column and row 6 of count(count) column as well. I just need to replace column only.
Struggling with this issue for a while and need your help. Is there a way to use RegEx in Value mapping? How would I refer Value column using this. Please help. It’s a show stopper for me.
Thanks!


Try Override to that specific field name then add value mapping with range 3 4
