Group Trend Display
The Group Trend Display,
Group trends are displayed on three full-width graphs. Each graph shows trends for
up to four loops, and is accompanied by the corresponding status blocks. The most
current trend sample is on the right side of the grid. MOD 300 trend buffers are
supported and the most recent 300 points are read if a Log Configuration aspect is
configured for the tag.

Group Trend Graph
Each of the four tags on a graph can have its own vertical scale (if limits are
different) with the upper and lower ranges displayed next to the trend graph. A
maximum of 300 data points can be trended for each tag. To display the value of a
point on a trend graph numerically, click on a trend trace.
Each trend line in a graph is color coded to match its tag and range color. The
context menu for the trend is the same as for the standard trend.
