Common problems
Start from the visible symptom. Change one thing at a time and check again.
A chart is empty
- Wait and look for a loading message.
- Refresh the dashboard once.
- Review the date range.
- Remove overly strict filters.
- If it fails for one person, check source permission.
Someone opens the dashboard but sees “access denied”
Review in this order:
- Does the link point to the correct content?
- Does the person belong to an allowed role?
- Does that role have
datasource accessfor every source?
See the three keys.
I cannot find sensor_data
Do not choose a similar source to keep going. It may produce a convincing chart with the wrong data. Ask an administrator for robotic.sensor_data access.
The line has too many points
- Increase time grain from minute to hour.
- Reduce the time range.
- Update and confirm the trend still answers your question.
The CSV does not match what I expected
- Confirm whether you exported the dashboard or individual chart.
- Review filters and time range before downloading.
- Open the file and validate headers and dates.
See Export chart data.
The report PNG is too long
Height usually comes from dashboard layout, not chat or email.
- Edit the dashboard.
- Remove empty rows and spaces.
- Move charts upward.
- Test the report again.
An option is missing
Functions depend on your role. Record:
- your username;
- the exact dashboard or chart name;
- the action you tried;
- the approximate time;
- the visible message, without your password.
Give this information to your administrator.
