@Gusta - Application Insights Overview Dashboard has been revamped. The legacy tile has been deprecated some time ago. So the recommendation is to use dashboards with multiple Metrics chart tiles. To get a "compact view", in the Chart Settings you can hide the title and move the legend to the right. Resize the chart on the dashboard to become a one-dashboard-tile-unit in height. Place other charts aligned vertically on the same dashboard.
Hope this information helps. Please revert back if you have any further queries. Thank you
