We just added a new report to help businesses understand their shipping performance - you can see the delivery status breakdown for the shipments of a specific date period. For example, for a healthy business, you should see most older shipments got delivered - if not you should start drilling down to find out any missed shipments.
It shows a stacked bar chart when the date range less than 2 weeks. It changes to a stacked line chart when it is over 2 weeks.
