Tag aliasing: Alias using [[tag_...]] or $tag_... not changing to tag

We have a problem trying to alias by Tag in our dashboards.
In the documentation we see that using $tag_ should work - but it displays literally as its named instead of changing. - Please see attached screenshot of Grid and Piechart.

I have searched on this and seen some comments about having it in the group by also - but it makes no difference. I also have tried using the [[ ]] method, and it didn’t change either.

Thank you in advance for any help you can provide.

After a week of investigation we have found the issue - we are going through a proxy to our database, and we were stripping out the tags when serializing the result from the influx api.

This can be closed now :slight_smile:
