The Trend Viewer
Viewing Trends with Drag-and-Drop
Expand the tree in an Explorer until you reach the desired tag, then drag and
drop it into an open Trend viewer. After a short delay, the tag’s plot is displayed
in the Trend viewer. Figure 34 shows a Trend viewer displaying data for several
tags. Notice that each tag in the graph displays in the color designated for it in
the Legend that is to the left of the graph. You’ll also see that the Y axis color is
linked to the tag color, but you can change that in the trend’s properties (see
page 34).
