The PLT program generates plots that are defined by pltfiles. Pltfiles are ASCII files with a keyword, a transfer of control, a numeric parameter, a string parameter, a message, a macro, or data values on each line.
Symbols, Line Types, Area Fill Patterns, and Colors
The maximum number of characters on any input line is 1024. The maximum number of data columns is 64.
Keywords have no arguments or values associated with them, but cause an action or change of mode. Only the first four characters are necessary to specify a keyword.

______________________________
Note 1: Negative values select absolute line weights, positive values multiply the default line weight, and zero eliminates the lines.
Note 2: Positive values are used as multipliers of default size. Negative values are used as absolute size in inches.
Note 3: YES = Y = 1 and NO = N = 0.
Note 4: Intervals for tic marks are of the form MM.N where MM and N are the number of major and minor intervals respectively. Zero value indicates axis line with no tick marks.
Note 5: If set to zero no annotations are to be skipped. Positive values indicate the number of annotations to be skipped. The first digit after the decimal point indicates an offset to the first annotation not skipped. Negative values produce no annotations.
Note 6: The interpretation of color is device dependent. A small positive value selects a pen number (1-9) on pen plotter devices (HPGL and Tektronix) and selects a predefined color index (0-15) on other devices that support color output (PC, PostScript, and CGM). A negative value for FGCOL, BGCOL, or FNCOL indicates that device default colors should be used. A negative value for all other color parameters indicates that the color should be set to the same value as FGCOL.
Note 7: The line pattern size controls the length of the dash plus space for line types greater than (or equal to) 1. Negative values select absolute pattern size in inches, positive values multiply the default pattern size.
Note 8: A negative value for this parameter indicates the fill color should be the same value as PLTCOL. A positive value is an index into the PLT color palette.
Note 9: Arrowheads are only drawn for PLTYPE=2 (lines). If AROTIP is greater than 0, then arrowhead will be filled with color specified by SHDCOL.
String parameters are followed by an equal sign and a string. Only the first four characters are necessary to specify a parameter name. The default value of all string parameters is a NULL string.

The parameters XDATA, YDATA, and ZDATA are interpreted as arithmetic expressions that may include column numbers, which are specified as $1, $2, …, $64.
Messages are quoted strings, which may be several lines long. The position of the message may be specified immediately preceding the open quote on the first line of the message or by setting the parameters MXLLC and MYLLC.
Macros are invoked by a line that begins with "%macro_name" followed by up to 99 arguments (delimited by spaces). There are five internal macros, %define, %undefine, %repeat, %for, and %msg.
%define <macro_name>
New macros may be defined using the %define macro. The first argument of %define is the new macro name (without the % character) and the second argument may contain the body of the new macro. If the %define macro has no second argument, the body of the new macro will be obtained from the succeeding lines of the pltfile up to a line that begins with “%%". Occurrences of $1, $2 ... $99 within the body of the macro are replaced by arguments when the new macro is invoked.
%undefine <macro_name>
The %undefine macro removes the macro definition.
%msg <x> <y> <format> …
Formatted messages are produced by the %msg macro. The first two arguments are the x and y locations used to located the message on the plot. The third argument is a format string, which may contain C-style, floating-point format specifications embedded in text. For each floating-point specification in the format string, there should be an additional argument with an arithmetic expression for the value of the corresponding floating-point number.
%repeat <count>
The %repeat macro is similar to the %define macro except that the first argument is a repeat count instead of a new macro name. Any occurrence of $0 in the macro body will be replaced by an index of the current iteration.
%for <item> …
The %for macro is similar to the %repeat macro except that the number of repetitions is determined by the number of arguments on the first line. Any occurrence of $0 in the macro body of %for will be replaced by an index of the current iteration. Any occurrence of $1 in the body of %for will be replaced by the corresponding argument on the first line.
In addition to these internal macros, PLT has one pre-installed macro. A pre-stalled macro differs from an internal macro in that its definition can be replaced by a new definition or removed by %undefine.
%straline <slope> <y_intercept> <lintype> <x1> <x2>
draws a line between x1 and x2 with the specified slope, y_intercept, and lintype, also assigns to the variables a & b the y-values at x1 & x2.
Any macro that is defined by a single arithmetic statement may also be used as a function within another arithmetic statement. Functions are invoked by the function name followed by parentheses. Any function arguments are delimited by commas within the parentheses. In addition to user-defined functions, there are several internally defined functions:
abs(x) |
absolute value of x |

$y_max |
maximum value of y-data |
$y_mean |

There are three additional internal variables:
$device |
number of the current output device |
$random |
random number, uniformly distributed between zero and one. |
$x |
current x-data value, useful for defining y=f($x) |
$y |
current y-data value |
$z |
current z-data value |
The internal definitions that plt program normally uses for symbols and text characters can be replaced by loading external definitions from plt font files. Use SYMFNT to redefine symbols, STDFNT to redefine the standard character set and ALTFNT to replace the alternate character set (usually Greek letters). The plt font files are created and modified by a separate program called PLTFNT.
Plt can read binary data files using the BDATA command. The binary data file must have a short header followed by integer data values. All integer values are assumed to stored in the file with the least-significant byte first. (This is the standard integer storage on the PC.) The header contains four two-byte integers: (1) a magic number for identification = 12345 decimal, (2) the number of bytes per integer value in the data (must be 2), (3) the number of coordinate values (x, y, z) to be specified for each data point (must be 1, 2, or 3), and (4) the number of data points in the file.
Some characters have special meaning in messages or labels.
[str] |
Subscript str. |
{str} |
Superscript str. |
^str^ |
Shift to alternate font for str. |
|str| |
If str is null or "*", then the current symbol is inserted. If str is a number (0-31), then the symbol with the corresponding number is inserted. If the number is preceded by an '_' then a line with corresponding line type is inserted. If the number is preceded by a '#' then a box with corresponding shade type is inserted. Otherwise, str and the surrounding "|" are taken literally. |
$ |
Replace "$" in string with space. |
; |
Begin comment. |

Arithmetic expressions may also include the name of any numeric parameter, internal variable, internal function, or single-line, user-defined macro. The value of any numeric parameter may be specified as an arithmetic expression. When specifying a numeric parameter, if the first character is “n” or “y”, the value is taken to be 0 or 1, respectively. Certain numeric parameters (mhalign, mvalign, pltype, and ticdir) give additional special meaning to the first character.
Several string parameters (xdata, ydata, zdata, and select) may also be specified by arithmetic expressions. The evaluation of these expressions is deferred until data is read. Data columns are referenced within these expressions as $1, $2, …, $64. Data rows may be conditionally included by a specifying a logical expression for the select parameter.
