Adding two or more items to a graph, all gets the same unit from the last added item.

[tjswe]

Describe the bug If you add multiple items to a graph, all items gets the unit from the last added item.

(Im a basic user but im pretty sure this has worked before)

Example: Monitoring a UPS Adding "Battery temperature" to a new graph, the data is i C (Celcius) Adding another item, "Battery Voltage", both items are now i V (Volt) Overriding unit in Grafana does not work.

Expected behavior Adding "Battery temperature" to a new graph, the data is i C (Celcius) Adding another item, "Battery Voltage", each item retain their unit, C (Celcius) and V (Volt)

Network data (I can not see where the unit is declared, perhaps not in this query?)
