I have created an Easy Chart in Vision and dropped a History tag onto the chart.
The chart works fine in designer, however when I run the vision project, chart is shaded red with DB fault indication in top left corner.
- Legacy DB Connection is enabled for the vision client
- MySQL database is connection is "valid" with 0.9 queries/s
- Tag is History Enabled and quality is good
Any points to investigate would be very appreciated!
Look in the diagnostics console in the client (via the help menu). It might show errors with clues.
Thanks for that pturmel! I have only been using Perspective so far (Maker Edition) so i didnt know about the diag console...

Caused by: com.inductiveautomation.ignition.client.gateway_interface.GatewayException: Error executing function 'QueryTagDensity': The current user does not have the required roles for this operation.
Ill dig deeper into the client permissions tonight.
That was exactly the issue..
I ended up enabling all permissions which worked, then deselecting one-by-one to find it. I should have just read the label..
