71 SHELL <strong>gnuplot</strong> 4.3 149<br />
70.116 Ztics<br />
The set ztics command controls major (labelled) tics on the z axis. Please see set xtics (p. 143) for<br />
details.<br />
70.117 Cblabel<br />
This command sets the label for the color box axis. Please see set xlabel (p. 141).<br />
70.118 Cbmtics<br />
The set cbmtics command changes tics on the color box axis to months of the year. Please see set<br />
xmtics (p. 142) for details.<br />
70.119 Cbrange<br />
The set cbrange command sets the range of values which are colored using the current palette by<br />
styles with pm3d, with image and with palette. Values outside of the color range use color of the<br />
nearest extreme.<br />
If the cb-axis is autoscaled in splot, then the colorbox range is taken from zrange. Points drawn in<br />
splot ... pm3d|palette can be filtered by using different zrange and cbrange.<br />
Please see set xrange (p. 142) for details on set cbrange (p. 149) syntax. See also set palette<br />
(p. 122) and set colorbox (p. 93).<br />
70.120 Cbtics<br />
The set cbtics command controls major (labelled) tics on the color box axis. Please see set xtics<br />
(p. 143) for details.<br />
71 Shell<br />
The shell command spawns an interactive shell. To return to <strong>gnuplot</strong>, type logout if using VMS, exit<br />
or the END-OF-FILE character if using Unix, endcli if using AmigaOS, or exit if using MS-DOS or<br />
OS/2.<br />
There are two ways of spawning a shell command: using system command or via ! ($ if using VMS).<br />
The former command takes a string as a parameter and thus it can be used anywhere among other<br />
<strong>gnuplot</strong> commands, while the latter syntax requires to be the only command on the line. Control will<br />
return immediately to <strong>gnuplot</strong> after this command is executed. For example, in AmigaOS, MS-DOS or<br />
OS/2,<br />
! dir<br />
or<br />
system "dir"<br />
prints a directory listing and then returns to <strong>gnuplot</strong>.<br />
Other examples of the former syntax:<br />
system "date"; set time; plot "a.dat"<br />
print=1; if (print) replot; set out; system "lpr x.ps"<br />
On an Atari, the ! command first checks whether a shell is already loaded and uses it, if available. This<br />
is practical if <strong>gnuplot</strong> is run from gulam, for example.
