I just started using Grafana and I’m working my way through it and I have stumbled on this issue.
I have a simple query that returns the number os ticket that were opened in a queue per day.
The query itself works okay and shows me the expected result, see below:
But the graph panel on Grafana shows data only until November 11th and the way it’s showing the data is not good for readability, I was expecting to have X bars corresponding to the number of queues I have.
I created two new tickets on Nov 17th and grafana simply does not show them as the query shows.
I had a very similar problem - data was not shown for the last hours/days although it was in the database. Which version of Grafana are you using? For me it worked when I got back to 5.2.2. Maybe you can try this.
