I have Grafana 6.6.2 and wrote an expression dependency but it doesn’t seem to work.
Basically the second expression depends on the first expression however the $Device is never populated when I select in the dashboard as below.
Other things I have tried:
- Changing floor to multiple selection
- Changing the WHERE condition to $Floor
The second query works fine if I replace it with a constant such as “location” = ‘Kitchen’, so it seems to be a bug of some sort.
Any advice to sort this out?
