SECTION 3. GRAPHTERM

3.3.7 COLLECT DATA
This option allows a collection interval to be
entered. While in the monitor or Graph Mode,
GT will automatically collect data on the interval
entered. Simply pressing "Enter" in response to
the request for an interval forces immediate
data collection. Section 3.2.8 discusses the
datafile format.
3.3.8 S
−−−−
SOUND
"S" toggles sound on and off. With sound on,
unique tones signal data collection, a flag going
high, a flag going low, and view save.
3.4. G
−−−−
GRAPHICS MODE
The "G" option acts as a toggle to either enter
or exit the Graphics Mode. All graphs are
displayed as per the current Graph
Specifications file (See the "L" option). Once in
Graphics Mode, the following options are
available:
3.4.1 H
−−−−
HELPS SHOW/REMOVE
"H" acts as a toggle that will either display or
hide the help box in the upper right hand corner
of the graphics screen.
3.4.2 G
−−−−
GRAPH ENTER/EXIT
"G" acts as a toggle to either enter or exit the
Graphics Mode.
3.4.3 R
−−−−
RE-SCALE
Causes all graphs that are set to auto-scaling to
be re-scaled. In other words, any value that has
gone off scale will be re-scaled to a power of ten
that will allow them to fit on the graph. The "R"
command has no effect on a fixed scale graph. A
full height vertical line is drawn on each auto-
scale graph to mark the re-scaling position.
3.4.4 "+"
−−−−
INCREMENT FIXED SCALE
Increments the power of ten of the first graph
that is in the auto-scale mode. This "forces" all
inputs to be displayed in the same power of ten,
thus enabling a quick view of the absolute
relationships between them.
3.4.5 "

"
−−−−
DECREMENT FIXED SCALE
Decrements the power of ten of the first graph
that is in the auto-scale mode. This "forces" all
inputs to be displayed in the same power of ten,
thus enabling a quick view of the absolute
relationships between them.
3.4.6 D
−−−−
DIGITS DISPLAYED
The default resolution of data displayed data is
3 digits; by pressing the "D" key, an additional
digit will be displayed. A maximum of 6 digits
can be displayed.
3.4.7 L
−−−−
L (GRAPH SPECIFICATION SCREEN)
The ability to graph up to all three graphs
simultaneously depends on the graphics
adapter in the computer. VGA can display up to
three graphs; EGA and Hercules will display up
to two, and CGA will display one graph. The
input locations to be displayed in each
column/graph are controlled by the "L" option.
When the "L" option is selected, the Graph
Specification Screen will be displayed. This is
where the each graph is defined in terms of
what input locations to display digitally and
graphically, whether to emphasize bar graphs or
trend plots, the name of the graph specifications
file, the graphing interval, and y-axis scaling
with upper and lower limits.
To move the cursor to the desired parameters,
use the "UP ARROW" and "DOWN ARROW"
keys. As you move from parameter to
parameter, notice that there is a highlighted
Help Line at the top of the display that provides
specific information and limitations for the
current parameter. Enter or edit the setting for
any parameter by typing the desired entry. The
current setting will be deleted and replaced with
what you type. The "DEL" key acts as a toggle
and will either delete or restore the current
setting. The "BACKSPACE" key will delete one
character at a time of the setting. These
command keys, their functions, and the Help
Line are all displayed for quick reference at the
top of the Graph Specification Screen.
Type ^P (control and P keys) to save the setup
file to disk and return to the monitor mode.
Pressing escape will return to the monitor mode
without saving the setup file. If the setup file
has not already been saved it will be saved if
the graphics mode is entered.
The following is a description of each of the
parameters that appear on the Graph
Specification Screen.
Graph Setup File: This is the filename (with a
.LOC extension automatically added) under
which the current graph specifications will be
saved when ^P is entered or when the graphics
mode is entered. The file StationFilename.LOC
also contains the last graph specifications that
