[Feature Request] Hide Null Value fields

[AImXOo0o]

Hello! :)

We have 3 Windows Terminal Servers (WTS) in our company.
I want one or three panels to show how many users are logged in on the WTS.
The problem is that I only want to see the online users. Not the offline users or users with no data.

There is the option "Hide if value is below" but this is not working. Even if I set Null Value as 0 or 6 etc. I guess this is only text ofc.

Is there a way to hide null data fields?

I am using a PRTG Plugin for Grafana.

Would be cool if there was an option to hide null data fields or set a "real" numeric value for null data.

Thanks in Advance!
