- Here is the URL for you to create your own Analytics Views.
http://<YourServerName>/<YourCollectionName>/<YourProjectName>/_analytics
- There are some out-of-box view you can start using as well.

- You’ll need permissions to create, edit, and delete those views.

- To download Power BI desktop, go to https://powerbi.microsoft.com/en-us/downloads/
- To get data from those views, please select “Azure DevOps Server (Beta)” from “Online Service”

- Then provide the collection URL and Team Project name
- Then Select view(s) to load

- After that, you can start drag and drop and slice and dice your data.

- You can also leverage oData query to create your own data set. There are some documents and samples: https://docs.microsoft.com/en-us/azure/devops/report/powerbi/overview?view=azure-devops
- For example, for an Open Bugs report, you can use the following query
let
Source = OData.Feed (“http://<YourServerName>/<YourCollectionName>/<YourProjectName>/_odata/v1.0/WorkItems?”
&”$filter=WorkItemType eq ‘Bug’ “
&”and StateCategory ne ‘Completed’ “
&”and startswith(Area/AreaPath,'<YourAreaPath>’) “
&”&$select=WorkItemId,Title,WorkItemType,State,Severity,AreaSK “
&”&$expand=AssignedTo($select=UserName),Iteration($select=IterationPath),Area($select=AreaPath) “
,null, [Implementation=”2.0″,OmitValues = ODataOmitValues.Nulls,ODataVersion = 4])
in
Source
- Then you have a matrix for Open Bugs

Hope this can help.
