70 SET-SHOW gnuplot 4.3 99
set dummy u,v
set dummy ,s
The second example sets the second variable to s.
70.18 Encoding
The set encoding command selects a character encoding. Syntax:
set encoding {}
set encoding locale
show encoding
Valid values are
default - tells a terminal to use its default encoding
iso_8859_1 - the most common Western European font used by many
Unix workstations and by MS-Windows. This encoding is
known in the PostScript world as ’ISO-Latin1’.
iso_8859_2 - used in Central and Eastern Europe
iso_8859_15 - a variant of iso_8859_1 that includes the Euro symbol
koi8r - popular Unix cyrillic encoding
koi8u - ukrainian Unix cyrillic encoding
cp437 - codepage for MS-DOS
cp850 - codepage for OS/2, Western Europe
cp852 - codepage for OS/2, Central and Eastern Europe
cp1250 - codepage for MS Windows, Central and Eastern Europe
The command set encoding locale is different from the other options. It attempts to determine the
current locale from the runtime environment. On most systems this is controlled by the environmental
variables LC ALL, LC CTYPE, or LANG. This mechanism is necessary, for example, to pass multibyte
character encodings such as UTF-8 or EUC JP to the wxt and cairopdf terminals. This command does
not affect the locale-specific representation of dates or numbers. See also set locale (p. 111) and set
decimalsign (p. 97).
Generally you must set the encoding before setting the terminal type. Note that encoding is not supported
by all terminal drivers and that the device must be able to produce the desired non-standard
characters.
70.19 Fit
The fit setting defines where the fit command writes its output. If this option was built into your version
of gnuplot, it also controls whether parameter errors from the fit will be written into variables.
Syntax:
set fit {logfile {""}} {{no}errorvariables}
unset fit
show fit
The argument must be enclosed in single or double quotes.
If no filename is given or unset fit is used the log file is reset to its default value "fit.log" or the value
of the environmental variable FIT LOG.
Users of DOS-like platforms should note that the \ character has special significance in double-quoted
strings, so single-quotes should be used for filenames in different directories, or you have to write \\ for
each \. Or you can just use forward slashes, even though this is DOS.
If the given logfile name ends with a / or \, it is interpreted to be a directory name, and the actual
filename will be "fit.log" in that directory.
If the errorvariables option is turned on, the error of each fitted parameter computed by fit will be
copied to a user-defined variable whose name is formed by appending " err" to the name of the parameter
