Grafana 7 bar chart value name

Hello,

I have upgraded our Grafana from 6.x to 7.0.3 (docker sha256:d72946c8e5d57a9a121bcc3ae8e4a8ccab96960d81031d18a4c31ad1f7aea03e). Everything works except my bar chart. I have a dashboard with SSL certificate expiry times that we have on the monitoring TV near our desks. It is a table (not timeseries) that has the domain name and the expiry time in seconds. I have tried setting the “Display name” field on the “Field” tab to $__cell_0, ${**cell_0}, ${__series.name} and ${**field.name} to absolutely no result. If I put any of those values to the Display name field, it says “No data” in the bar chart. Is this a bug? Am I doing something wrong? Are my settings wrong? It did work on the previous 6.x release. Thanks for your help guys.

can’t post more than two pics, so here’s the 3rd one

And it is the same story no matter what I put in the Display name field.
