Vehicle Activity graph ends on a different day for the 30-day view and the 90-day view.
This issue is on the Vehicle Activity graph on the Vehicle Details page in IVM. The difference is due to the way the data is processed. We allow the date to show as is for the 7 day and 30 day reporting. But on the 90 day reporting we have to summarize the data. We summarized the data to Monday. So it will always end on the most recent past Monday.
