70 SET-SHOW gnuplot 4.3 111
70.30 Lmargin
The command set lmargin sets the size of the left margin. Please see set margin (p. 112) for details.
70.31 Loadpath
The loadpath setting defines additional locations for data and command files searched by the call,
load, plot and splot commands. If a file cannot be found in the current directory, the directories in
loadpath are tried.
Syntax:
set loadpath {"pathlist1" {"pathlist2"...}}
show loadpath
Path names may be entered as single directory names, or as a list of path names separated by a platformspecific
path separator, eg. colon (’:’) on Unix, semicolon (’;’) on DOS/Windows/OS/2/Amiga platforms.
The show loadpath, save and save set commands replace the platform-specific separator with
a space character (’ ’) for maximum portability.
If the environment variable GNUPLOT LIB is set, its contents are appended to loadpath. However,
show loadpath prints the contents of user defined loadpath and system loadpath separately. Also, the
save and save set commands save only the user specified parts of loadpath, for portability reasons.
70.32 Locale
The locale setting determines the language with which {x,y,z}{d,m}tics will write the days and
months.
Syntax:
set locale {""}
may be any language designation acceptable to your installation. See your system documentation
for the available options. The default value is determined from the LC TIME, LC ALL, or LANG
environment variables.
To change the decimal point locale, see set decimalsign (p. 97). To change the character encoding to
the current locale, see set encoding (p. 99).
70.33 Logscale
Syntax:
set logscale
unset logscale
show logscale
where may be any combinations of x, x2, y, y2, z, and cb in any order, and where is
the base of the log scaling. If is not given, then 10 is assumed. If is not given, then all
axes are assumed. The command unset logscale turns off log scaling for the specified axes.
Examples:
To enable log scaling in both x and z axes:
set logscale xz
To enable scaling log base 2 of the y axis:
set logscale y 2
To enable z and color log axes for a pm3d plot:
set logscale zcb
To disable z axis log scaling:
unset logscale z
