I am using influxdb to store my data. In Grafana, I created variable from tag, that works fine. When I create variable from field, it stops working. Variable
fk , shortcut for field key, can be
price. When I check generated query, it looks like this:
SELECT "/^amount$/" FROM "history"
I log to influxdb and test it, the result is empty. When I change it to:
SELECT "amount" FROM "history"
I can see some results. My questions is, why field variable does not work?
