Using Trend Display
Trend display is used to plot traces in a graphical manner. The 800xA History server
collects historical data from 800xA System, which can be plotted in a trend display.
For visualizing seamless trends a basic history log should be created along with the
800xA History log in the 800xA History Log template.
The minimum time of the Basic History log and the 800xA History log update rate
should be the same.
