SECTION 3. GRAPHTERM
3-9
3.4.9 F1..F8
−−−−
FLAG TOGGLE
The user flag status is shown in the upper right
hand corner of the graphics screen. Set flags
have their corresponding number displayed.
Keys F1 through F8 toggle user flags 1 through
8 respectively. (i.e., If the flag is set, the
function key will reset it. If the flag is reset the
function key will set it.)
3.4.10 P1..P8
−−−−
TOGGLE PORTS
When a port is set high (5 volts), the
corresponding number will be displayed in the
upper left hand corner of the graphics screen;
the user can set port 1 high or low by pressing
the "P" and then the "1" key.
3.4.11 C
−−−−
COLLECT DATA
This option is identical to the "U" command on
the main menu. Refer to Section 3.2.8 for
details on the "C" command.
3.4.12 W
−−−−
SWEEP GRAPH TOGGLE
Toggles the graphs between the standard strip
chart displays and sweep graph displays. The
standard display draws new data on the right
hand side of the display and scrolls older data
to the left. The sweep display draws new data
from left to right. The graphs are erased when
toggled.
3.5. COMMAND LINE PARAMETERS
GraphTerm allows command line parameters.
Several options are only available from the
command line. The command line can be
incorporated into a batch file (extension ".BAT")
for repeated execution.
Standard commands are entered in the
sequence that they would be issued in running
the program a step at a time. For example, the
command
GT d:\path\station D d:\path\program M Q
runs GraphTerm, calls the datalogger at the
selected station, programs it from the
designated program file, then monitors input
locations with labels from the program file.
When Escape is pressed or communication
with the datalogger is broken, GraphTerm ends.
Separate command line parameters with
spaces. The command line can be up to 128
characters long. Commands like "C" can be
spelled out to "Call", or "D" to "Download" on the
command line. Only the first letter of the word
is used by GraphTerm. Another example is:
GT stnfile Monitor progfile Locations
specfile Graphics
would call the station using "stnfile" filename
then graphically monitor the input locations as
defined in the graph specifications file named
"specfile" with labels from, "progfile".
3.5.1 ADDITIONAL OPTIONS
The key words for these options must be entered
before the station file name. The key words are
case insensitive; if more than one is invoked, run
the key words together without spaces.
GraphTerm supports five additional command
line options. The key words are:
EGA
−
Disables the automatic hardware detection
feature of GraphTerm and forces power-up in EGA
mode. This option is only available when using
VGA hardware and is intended to provide the
means for enlarging the graphs and text for easier
viewing. Remember that EGA mode only allows 2
graphs.
MONO
−
Disables the color capability (default
setting) of GraphTerm. Laptop computers and
monochrome displays can be difficult to view when
colors are converted to shades of grey. This
option forces GraphTerm into monochrome mode
where all output is in one "color".
SYMBOLS
−
Attaches a symbol (the first letter of
each corresponding input location label)
periodically to the trend. GraphTerm defaults to no
symbols. When invoked, each symbol is attached
just below and to the right of the current data point
of the trend.
PIXEL
−
Disables the drawing of lines between
successive data points and uses a single pixel
for each data point instead.
GAPS
−
When invoked, if the trend is interrupted
for any reason and then resumed, GraphTerm will
not draw a line between the last point and the
current point (thereby leaving a noticeable gap on
the trend).
Some examples of these commands are:
GT MonoEGAsymbols stnfile M progfile L
graphspecfile G
This example sets GraphTerm to monochrome
and EGA modes, and displays symbols on the
graphs; GraphTerm then calls the station using
"stnfile" filename and graphics the input locations
as defined in the graph specifications file named
"graphspecfile" with labels from, "progfile".
