On the home page, you will see displayed a break-down of the total number of .NET versions. You can either view this information in the chart on the left-hand side of the dashboard or in the handy table format on the right-hand side.
The chart and table are interactive, so if you drillthrough on a specific item, you will see its related page. The footer on all of the pages tells you when the .NET data was last refreshed (queried and imported into Power BI from SCCM).
Power BI, by default, displays all results. Once a filter is selected, for example, the Collection Name, it remains in place until replaced by another filter. Filters are generally enabled when you drillthrough from one page to another page.
