140 <strong>gnuplot</strong> 4.3 70 SET-SHOW<br />
70.80 X2mtics<br />
The set x2mtics command changes tics on the x2 (top) axis to months of the year. Please see set<br />
xmtics (p. 142) for details.<br />
70.81 X2range<br />
The set x2range command sets the horizontal range that will be displayed on the x2 (top) axis. Please<br />
see set xrange (p. 142) for details.<br />
70.82 X2tics<br />
The set x2tics command controls major (labelled) tics on the x2 (top) axis.<br />
(p. 143) for details.<br />
Please see set xtics<br />
70.83 X2zeroaxis<br />
The set x2zeroaxis command draws a line at the origin of the x2 (top) axis (y2 = 0). For details,<br />
please see set zeroaxis (p. 148).<br />
70.84 Xdata<br />
This command sets the datatype on the x axis to time/date. A similar command does the same thing<br />
for each of the other axes.<br />
Syntax:<br />
set xdata {time}<br />
show xdata<br />
The same syntax applies to ydata, zdata, x2data, y2data and cbdata.<br />
The time option signals that the datatype is indeed time/date.<br />
datatype reverts to normal.<br />
If the option is not specified, the<br />
See set timefmt (p. 137) to tell <strong>gnuplot</strong> how to read date or time data. The time/date is converted<br />
to seconds from start of the century. There is currently only one timefmt, which implies that all the<br />
time/date columns must conform to this format. Specification of ranges should be supplied as quoted<br />
strings according to this format to avoid interpretation of the time/date as an expression.<br />
The function ’strftime’ (type "man strftime" on unix to look it up) is used to print tic-mark labels.<br />
<strong>gnuplot</strong> tries to figure out a reasonable format for this unless the set format x "string" has supplied<br />
something that does not look like a decimal format (more than one ’%’ or neither %f nor %g).<br />
See also Time/date (p. 39) for more information.<br />
70.85 Xdtics<br />
The set xdtics commands converts the x-axis tic marks to days of the week where 0=Sun and 6=Sat.<br />
Overflows are converted modulo 7 to dates. set noxdtics returns the labels to their default values.<br />
Similar commands do the same things for the other axes.<br />
Syntax:<br />
set xdtics<br />
unset xdtics<br />
show xdtics<br />
The same syntax applies to ydtics, zdtics, x2dtics, y2dtics and cbdtics.<br />
See also the set format (p. 100) command.
