The Trend tab contains navigation controls which allow you to navigate historical data trends and refresh the view as required:
| Icon | Description |
|---|---|
| Adjust the trend time frame by increments of 1/4. For example, if you are viewing 6 hours of data, the frame moves forward or back 1.5 hours; if you are viewing 1 month of data, the frame moves forward or back 1 week. The frame can only move forward up to the current time. | |
| Adjust the trend time frame by a full increment. For example, if you are viewing 6 hours of data, the frame moves forward or back 6 hours; if you are viewing 1 month of data, the frame moves forward or back 1 month. The frame can only move forward up to the current time. | |
| Show the most recent data (up to current date/time). | |
 |
Select this option to continuously update the trend with most current readings (this option has the same effect as pressing the button). |
 |
To see close-up trend details, click and drag across a trend line. Drag right to zoom in/drag left to zoom out. 
|
| Navigating or zooming within the trend graph automatically unchecks the Updates on option. As you navigate within the trend graph, you are then viewing historical data. |
