Hi, did you fix it? I have similar issues

Hi,

Try to use query inspector.
http://docs.grafana.org/guides/whats-new-in-v4-5/#query-inspector

You can also see your log to see if everything it’s ok.

Regards

Fixed, I had uploaded a pre-built dashboard which was pointing to a different data-source. Thanks
