Figure 4-5: Analog Trend Data
The second line of the screen shows the trend variable name and the
sampling mode, which can be average, maximum, minimum, or actual.
The third line of the screen shows the date, time, value, and units of
the currently selected sample. The currently selected sample is
indicated by a vertical line, which acts as a pointer or sample bar, and
is initially positioned at the latest sample, i.e., at the right hand side of
the plot. You can use the
and keys to move the pointer from
one sample to the next. When you move the pointer, the Date, Time,
and Value fields change to correspond to the selected sample.
Along the left side of the graph are two numbers indicating the high
and low range of the vertical axis of the plot. The default values of
high and low range are 100 and 0, respectively.
