I’m new to Grafana so I just installed it yesterday. I’ve created a pie chart from three Elasticsearch queries but I don’t see how I can label them correctly in the legend. There are no fields in Elasticsearch that represent what the queries are. These are phone calls and should be labeled something along the lines of ‘incoming’, ‘outgoing’ and ‘internal’. Yet, all fields simply show ‘count’. I’ve seen many other people have had issues getting the labels correct but none of the solutions I’ve found seem to apply to my exact situation.
