 - `$__interval` - Grafana calculates the minimum time grain that can be used to group by time in queries. More details on how it works [here]({{< relref "../../reference/templating.md#interval-variables" >}}). It returns a time grain like `5m` or `1h` that can be used in the bin function. E.g. `summarize count() by bin(TimeGenerated, $__interval)`

+Any Log Analytics query that returns a list of values can be used in the `Query` field in the Variable edit view. There is also one Grafana function for Log Analytics that returns a list of workspaces.

 Allowing a low dashboard refresh interval can cause severe load on data sources and Grafana. Grafana v6.7 allows you to restrict the dashboard refresh interval so it cannot be set lower than a given interval. This provides a way for administrators to control dashboard refresh behavior on a global level.

-### Stackdriver Project Selector
+### Stackdriver project selector
 A Stackdriver data source in Grafana is configured for one service account only. That service account is always associated with a default project in Google Cloud Platform (GCP). Depending on your setup in GCP, the service account might be granted access to more projects than just the default project. 
 
 In Grafana 6.7, the query editor has been enhanced with a project selector that makes it possible to query different projects without changing datasource. Many thanks [Eraac](https://github.com/Eraac), [eliaslaouiti](https://github.com/eliaslaouiti) and [NaurisSadovskis](https://github.com/NaurisSadovskis) for making this happen!
