What Grafana version and what operating system are you using?
AWS Managed Grafana, I see version v9.4.7 on the UI.
What are you trying to achieve?
Show a panel with data summed across multiple datasources.
How are you trying to achieve it?
I will use a datasource variable, which allows multi-select and all-select to select the datasources.
I have a bar chart.
My datasource variable appears as a drop down on the UI. If I select exactly 1 datasource, the data returned is correct. If I select more than 1 datasource, I notice the data returned is for only the first datasource selected as part of the variable.
What did you expect to happen?
I expect to get data from all datasources selected within the datasource drop down.
Can you copy/paste the configuration(s) that you are having problems with?
Here is my Query
Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were.
