I am using the druid plugin v0.0.5 and not having great luck with it. grafana 5.4.2 is installed. I can auto-discover datasources and dimensions just fine. The issue is displaying the metrics on the chart. The metrics are auto-discovered from the select statement but I am not seeing them with the topN. I manually enter a metric fieldName and I am still unable to see a chart drawn. Does anybody have some advice for working with druid as a datasource?
