No Data in Panel When Using Mixed Datasource After Upgrading to Grafana 11

Grafana Dashboards
1

Greetings,

After upgrading to Grafana 11, I’m experiencing an issue where my panels using the -- Mixed -- datasource always show “No Data”, even though it returns data in the Explore tab.

  • When using -- Mixed -- in a panel, it always displays “No Data”.
  • If I run the same query in Explore, I can see the expected data, but it is not rendered in the panel

The panel worked fine on Grafana v10.x, but the problems started after we upgraded to Grafana 11. Is this a known issue? Any pointers on fixing this would be much appreciated. Thanks!

I also seem to be hitting this. If I edit one of the visualisations on a dashboard it appears that no query request is done. In fact even if I change the PromQL and press “Run queries” no network requests are done. However, if I switch the source from -- Mixed -- to me Prometheus source and then back again, “Run queries” works
