10.2 Trend Graphs
Up to 11 user-selected data from among the individual outputs from each channel and
average concentration outputs, groups a, b, and c, can be viewed in graphical form at a
time in a single screen. To move to the trend graph display, touch the graph display key
on a basic panel display. The cascade function may be used to view each trend line of
channels clearly in the trend graph display. The function offsets the axes so that trend
lines do not overlap. The following describes graph setup.
