35 SAVE gnuplot 4.0 51<br />
unset key<br />
set yrange [0:10]<br />
set multiplot<br />
call ’plotter’ ’data’<br />
unset multiplot<br />
The result is a single graph consisting of five plots. The yrange must be set explicitly to guarantee that<br />
the five separate graphs (drawn on top of each other in multiplot mode) will have exactly the same axes.<br />
The linetype must be specified; otherwise all the plots would be drawn with the same type. See also<br />

34 Reset<br />
The reset command causes all graph-related options that can be set with the set command to take on<br />
their default values. This command is useful, e.g., to restore the default graph settings at the end of a<br />
command file, or to return to a defined state after lots of settings have been changed within a command<br />
file. Please refer to the set command to see the default values that the various options take.<br />
The following set commands do not change the graph status and are thus left unchanged: the terminal<br />
set with set term, the output file set with set output and directory paths set with set loadpath and<br />
set fontpath.<br />
35 Save<br />
The save command saves user-defined functions, variables, the set term status, all set options, or all<br />
of these, plus the last plot (splot) command to the specified file.<br />
Syntax:<br />
save<br />
{} ’’<br />
where is functions, variables, terminal or set. If no option is used, gnuplot saves functions,<br />
variables, set options and the last plot (splot) command.<br />
saved files are written in text format and may be read by the load command. For save with the<br />
set option or without any option, the terminal choice and the output filename are written out as a<br />
comment, to get an output file that works in other installations of gnuplot, without changes and without<br />
risk of unwillingly overwriting files.<br />
save terminal will write out just the terminal status, without the comment marker in front of it. This<br />
is mainly useful for switching the terminal setting for a short while, and getting back to the previously<br />
set terminal, afterwards, by loading the saved terminal status. Note that for a single gnuplot session<br />
you may rather use the other method of saving and restoring current terminal by the commands set<br />
term push and set term pop, see set term (p. 99).<br />
The filename must be enclosed in quotes.<br />
The special filename "-" may be used to save commands to standard output. On systems which support<br />
a popen function (Unix), the output of save can be piped through an external program by starting the<br />
file name with a ’|’. This provides a consistent interface to gnuplot’s internal settings to programs<br />
which communicate with gnuplot through a pipe. Please see "help batch/interactive" for more details.<br />
Examples:<br />
save ’work.gnu’<br />
save functions ’func.dat’<br />
save var ’var.dat’<br />
save set ’options.dat’<br />
save term ’myterm.gnu’<br />
save ’-’<br />
save ’|grep title >t.gp’
