Add horizontal line at average level on graph

I would like to add a horizontal line ( like the threshold line) but that will stay on the average value ?
How can i implement this ?



There isn’t any support for dynamic thresholds in Grafana yet (hopefully in the future). But depending on which data source you are using it might be possible to draw a line using a query.

For example, if you were using Graphite then it has an aggregateLine function for your use case:

It’s also possible with Prometheus using an Instant Query and a transform:
