 Instead of hard-coding things like server, application and sensor name in your metric queries you can use variables in their place. Variables are shown as dropdown select boxes at the top of the dashboard. These dropdowns make it easy to change the data being displayed in your dashboard.

 Grafana v8.0 changes the underlying data structure to [data frames]({{< relref "../developers/plugins/data-frames.md" >}}) for the Postgres, MySQL, Microsoft SQL Server data sources. As a result, a _Time series_ query result gets returned in a [wide format]({{< relref "../developers/plugins/data-frames.md#wide-format" >}}). To make the visualizations work as they did before, you might have to do some manual migrations.
 
 For any existing panels/visualizations using a _Time series_ query, where the time column is only needed for filtering the time range, for example, using the bar gauge or pie chart panel, we recommend that you use a _Table query_ instead and exclude the time column as a field in the response.

 Refer to this [issue comment](https://github.com/grafana/grafana/issues/35534#issuecomment-861519658) for detailed instructions and workarounds.
+
+#### Prefix added to series names
+
+When you have a query where there's a time value and a numeric value selected together with a string value that's not named _metric_, the graph panel renders series names as `value <hostname>` rather than just `<hostname>` which was the case before Grafana 8.
+
+```sql
+SELECT
+  $__timeGroup("createdAt",'10m'),
+  avg(value) as "value",
+  hostname
+FROM grafana_metric
+WHERE $__timeFilter("createdAt")
+GROUP BY time, hostname
+ORDER BY time
+```
+
+There are two possible workarounds to resolve this problem:
+
+1. In Grafana v8.0.3, use an alias of the string column selected as `metric`. for example, `hostname as metric`.
+2. Use the [Standard field options/Display name]({{< relref "../panels/standard-options.md#display-name" >}}) to format the alias. For the preceding example query, you would use `${__field.labels.hostname}` option.
+
