Customing Your Plot
1. When LOG starts up, it reads lplot.cnf in the /lib directory (ask
your local anaLOG maintainer), which contains certain commands for
setting up the plotting system. This file in turn reads pens.cnf,
which has mappings of colors onto pen numbers. Each of these
commands begins with "lplot:", which signifies that the command is
intended for the LOG plotting tool.
2. You can give these commands yourself, either while LOG is running
by pressing ":" and then typing, e.g., "lplot: size B", or by
including such a line in your own "log.cnf" file.
3. The most interesting configurable thing for the plotting tool
is color. LPLOT uses a two-step method for determining color.
Each kind of object has a particular "color-name". These
color names (like GATE or WIRE) are looked up in the color-name
table to produce a pen-name (like RED or BLACK), which in turn
is looked up in the pen-name table to get the actual pen
number to use for pen plotters.
4. The following commands may be used after the word "lplot:".
LPLOT: COLOR color-name pen-name
This maps a given color-name onto a given pen-name.
Standard pen names are "black", "red", "green",
"purple", "blue", "yellow", and "none" (which
suppresses drawing of that color). You can also
specify a second color-name in place of a pen-name,
in which case the first color-name uses the same
pen as the one which was recorded for the second.
Display a list of all color names that have been
recorded in "LPLOT: COLOR" commands.
Open up the plotter configuration attribute screen.
This is the same as touching "Config" while in the
LPLOT: DOTS gate-name gate-name ...
Undo the effect of previous "NODOTS" commands for
the specified gates.
LPLOT: FILE psfilename
Specify the filename for saving or printing a PostScript
plot. The ".ps" is automatically postpended.
LPLOT: FONT font-file
Use the specified font file for text. The default
file is "lplot.font" in the /lib directory for log.
LPLOT: INVISIBLE gate-name gate-name ...
Add the specified gates to the list of gates which
do not show up in plots. By default, TIME, NUMBERS,
and DIGH are on this list.
LPLOT: LABELFONT font-number
Specify the font number to use for text labels in
plots. For the standard font file, this should be
a number from 1 to 13. Common numbers are 1 for a
very simple font, 2 for a standard Roman font, and
3 for Roman italics. Default is 2.
LPLOT: NODOTS gate-name gate-name ...
Add the specified gates to the list of gates for
which extra solder blobs will not be generated.
By default, only the digital LED gate is on this
LPLOT: PENCOLOR pen-name pen-number
This specifies the mapping of pen names (such as RED or
BLACK) onto pen numbers for the plotter. The standard
configuration file "pens.cnf", which is included by all
the standard "log.cnf" files, contains good default
Display a list of all pen names that have been
recorded in "LPLOT: PENCOLOR" commands.
LPLOT: PLOTTER hpib-address
When using a pen plotter on the HPIB bus, this
command specifies the HPIB address of the plotter.
Default is 5.
LPLOT: PSFILE psfilename
Specify the filename or command for saving or
printing a PostScript plot. This can either be
a regular filename, such as "plot.ps", or a
filename piped to a command, such as
"/tmp/*.ps | lpr *" (the default).
LPLOT: SIGFONT font-number
Specify the font number to use for signal names
in plots. (See LABELFONT command.) Default is 2.
LPLOT: SIZE paper-size
Set the size for paper in pen plotters. Other output
devices, such as the laser printer, compute the size
on their own. Size A is standard 8.5" by 11" sheets;
size B is about 11" by 17". Size AUTO means to
compute the size automatically.
LPLOT: VISIBLE gate-name gate-name ...
Remove the specified names from the list of
5. Here is a list of gate-color names used by LPLOT. Where an
alternate name is given, LPLOT looks up that color-name if
the main color-name is not found. The ultimate default is
pen-name BLACK. Except for SCOPE and BORDER, all of these
apply only to circuit-diagram plots.
BORDER Color of the dotted border on the screen that indicates
the limits of the page. Default in "lplot.cnf"
DASHBOX (Alternate: LABELTEXT.) Color of "yellow boxes" (as
gotten from the Frills menu).
GATE Color of regular gates.
LABELTEXT (Alternate: DASHBOX.) Color of labels (as gotten
from the Frills menu).
NODE (Alternate: GATE.) Color of node names, drawn when
requested by the Options screen for gate plotting.
Node names are invented by LPLOT and do not
correspond to node names used by any other program.
OFFLED (Alternate: GATE.) Color of digital LED's and other
readouts which are "off". Default is YELLOW.
ONLED (Alternate: GATE.) Color of digital LED's and other
readouts which are "on". Default is RED.
SCOPE Color of data plots.
SIGNAL (Alternate: GATE.) Color of signal names in TO and FROM.
SOLDER (Alternate: WIRE.) Color of solder blobs.
WIRE Color of wires.
