Few months ago (April 21), I set up a Grafana instance for managing graph display of ‘big’ time based data set on Node-Red dashboard.
This worked perfectly.
For data treatement reasons, I used region creation throw the graph GUI (CTRL + drag-n-drop) then API requests to get info arround this region and process some data calculation.
To day, when a colleage managed to reuse this tool, it seams that annotation/region creation does not work any more:
- With CTRL + Click on graph, nothing happen at all
- With CTRL + Drag-n-Drop, only time zoom in processed
Unfortunately, I didn’t check Grafana version at the moment it worked well. And I cannot insure that ther have been any updates on this shared server (DEBIAN).
But today, I tried to upgrade it version 8, but nothing changed. And I tried to downgrade to 7.5.0 but nothing changed as well.
Please advice where I’m wrong, or where to have a look for retrieving annotation management through graph GUI.
