GNUPlot Manual

36 SET-SHOW gnuplot 4.0 75
unset label
To show all labels (in tag order), use:
show label
To set a label on a graph with a timeseries on the x axis, use, for example:
set timefmt "%d/%m/%y,%H:%M"
set label "Harvest" at "25/8/93",1
To display a freshly fitted parameter on the plot with the data and the fitted function, do this after the
fit, but before the plot:
set label ’a = %3.5g’,par_a at 30, 15
set label ’b = %s*10^%S’,par_b at 30, 20
To set a label displaced a little bit from a small point:
set label ’origin’ at 0,0 point lt 1 pt 2 ps 3 offset 1,-1
To set a label whose color matches the z value (in this case 5.5) of some point on a 3D splot colored
using pm3d:
set label ’text’ at 0,0,5.5 tc palette z
36.30 Lmargin
The command set lmargin sets the size of the left margin. Please see set margin (p. 77) for details.
36.31 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.
36.32 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 LANG environment variable.
