In Magento sales_order_aggregated_created database table is not getting updated after Magento updating from 1.5 to 1.9.2.1. so the report order is not working for day and month report. It shows data before Magento upgrade. Because of this chart is also working on the dashboard. P.S. I have used AITOC extension and extendware both.
p.p.s. I have used mageworx orders pro extension as well.
The solution is to use the lifetime statistic refresh instead of the daily statistic refresh.
