What is
displayed on a
trend?
A trend consists of the timed and threshold waveforms for the parameter on display.
Users have the option to enable/disable a trend or plot display, wherein display area
will resize according to the number of plots enabled for display. In addition, users have
the option to enable/disable channels to trend in a select parameter. Each parameter can
have one or multiple channels to plot.
The trend screen also features a Zoom box, wherein users can expand or narrow the
size of a zoomed area via touch and drag. The zoom feature allows users to view trend
coordinates of min, max and avg values in greater detail.
