Trend Usage

The Trend Display can present data seamlessly from both run-time and historical
data. When a Trend Display for an object is selected all available data can be viewed
via the trend. This also means that it is possible to move the time range back and
forth without worrying about where data is coming from provided that the seamless
function is enabled in the Trend Display. The Trend Display can hold a number of
Trend Traces and it is possible to trend any property. It is possible to insert new
traces for comparison with the existing in all trends but the modified trend can only
be saved if it is an Operator Trend. Functions for rulers, time zooming, magnifying
glass etc. are available in the Trend Display. The time-offset function can be used to
trace a signal in real time and compare it with values from yesterday. It is possible to
present trend relationship between two values as XY plots.

Accessing Trend Display

Two possible ways to access a Trend Display for an object are from a shortcut in the
Application Bar or from the context menu.
The Trend Display is divided into three areas: the Trend Area, the Tool Bar and the
Trend Table. See
