With the Live Trend feature you can trend the present value attribute of up to two points in real-time, even if the points do not have a trend configured. Live trending can be initiated by selecting the Live Trend option in the Point Details screen of any point from any location in the display, such as the Home screen or Equipment Data screen.

Samples are plotted every 30 seconds in addition to records of any change of value to show data on a graph over a five minute window with the latest 144 samples. When two points are added to the live trend, the active focus can be toggled between each point. When you toggle the point in focus, the screen updates to show the Y-axis for the point selected.
Live trend data continues to be displayed until the user navigates away from the view, or an idle timeout occurs. If the display idle time setting is set for less than 15 minutes, then it is extended to 15 minutes while viewing live trends. If a user's session expires in the next one minute, a popup is shown with the option to extend the session if you select OK. Otherwise, if the session expires, the Live Trend view closes and the user is logged out if they were previously logged in.
