By default, the real-time data mode displays the graphs with data for the last 7 days. Access Manager 5.0 onwards, the offline mode is not supported. You cannot migrate existing events in real-time and offline indices to this product.
You can add filters or refresh the data after a specific time duration. You can view data from the time Analytics Dashboard is configured till the present time, but the data that is older than 7 days is not displayed.
