GNUPlot Manual

36 SET-SHOW gnuplot 4.0 79
For some terminals, no plot is displayed until the command unset multiplot is given, which causes the
entire page to be drawn and then returns gnuplot to its normal single-plot mode. For other terminals,
each separate plot command produces a plot, but the screen may not be cleared between plots.
Any labels or arrows that have been defined will be drawn for each plot according to the current size
and origin (unless their coordinates are defined in the screen system). Just about everything else that
can be set is applied to each plot, too. If you want something to appear only once on the page, for
instance a single time stamp, you’ll need to put a set time/unset time pair around one of the plot,
splot or replot commands within the set multiplot/unset multiplot block.
The commands set origin and set size must be used to correctly position each plot; see set origin
(p. 80) and set size (p. 91) for details of their usage.
Example:
set size 0.7,0.7
set origin 0.1,0.1
set multiplot
set size 0.4,0.4
set origin 0.1,0.1
plot sin(x)
set size 0.2,0.2
set origin 0.5,0.5
plot cos(x)
unset multiplot
displays a plot of cos(x) stacked above a plot of sin(x). Note the initial set size and set origin.
While these are not always required, their inclusion is recommended. Some terminal drivers require
that bounding box information be available before any plots can be made, and the form given above
guarantees that the bounding box will include the entire plot array rather than just the bounding box
of the first plot.
set size and set origin refer to the entire plotting area used for each plot. If you want to have the
axes themselves line up, you can guarantee that the margins are the same size with the set margin
commands. See set margin (p. 77) for their use. Note that the margin settings are absolute, in
character units, so the appearance of the graph in the remaining space will depend on the screen size of
the display device, e.g., perhaps quite different on a video display and a printer. See also
multiplot demo (multiplt.dem).
36.38 Mx2tics
Minor tic marks along the x2 (top) axis are controlled by set mx2tics. Please see set mxtics (p. 79).
36.39 Mxtics
Minor tic marks along the x axis are controlled by set mxtics. They can be turned off with unset
mxtics. Similar commands control minor tics along the other axes.
Syntax:
set mxtics { | default}
unset mxtics
show mxtics
The same syntax applies to mytics, mztics, mx2tics, my2tics and mcbtics.
is the number of sub-intervals (NOT the number of minor tics) between major tics (the default
for a linear axis is either two or five depending on the major tics, so there are one or four minor tics
between major tics). Selecting default will return the number of minor ticks to its default value.
If the axis is logarithmic, the number of sub-intervals will be set to a reasonable number by default
(based upon the length of a decade). This will be overridden if is given. However the usual
