Zoom Out and Real-Time Data
By default, a view in a running test is in real-time mode and is set to auto scrolling. Until the test starts, the overview component has nothing to show. After the test starts and the statistics are delivered, the overview control starts updating itself. Over the entire test run, the overview control shows an overview of statistics back to the beginning of the test, but the sliding window gradually becomes smaller to show the latest history. When the auto-scroll option is on, both the sliding window and the detailed view scroll to the end.
If you perform any action that requires the zoom interval to be changed, the detailed view is updated to reflect the zoom interval and position, and it is not updated anymore when new real-time data comes in. However, the overview control is still updated with real-time data. In such cases, the auto-scroll option is automatically disabled.
If the data store option is disabled, you are still able to resize or move the sliding window. If no results are stored, no data is loaded.
