Annotations on hover within Grafana graphs?

I have a database datasource, and I want to display a graph. The graph I want is (time, benchmark_name, score), but I want additional things on each point, e.g. commit_hash, that I don’t want to be part of the timeseries, I just want it to be annotation data on each point. When I write a query, it’s generating individual time series for each commit_hash, but I just want one timeseries for each benchmark_name with the commit_hash as an annotation if you hover the individual points. Is that possible?

I don’t believe so. Every unique combination of label/value is going to be a separate series.
