70.40 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
minor tics (2, 3, ..., 8, 9 between 1 and 10, for example) are obtained by setting to 10, even
though there are but nine sub-intervals.
To set minor tics at arbitrary positions, use the ("" , ...)
{x|x2|y|y2|z}tics with empty and set to 1.
form of set
The set m{x|x2|y|y2|z}tics commands work only when there are uniformly spaced major tics. If all
major tics were placed explicitly by set {x|x2|y|y2|z}tics, then minor tic commands are ignored.
Implicit major tics and explicit minor tics can be combined using set {x|x2|y|y2|z}tics and set
{x|x2|y|y2|z}tics add.
Examples:
set xtics 0, 5, 10
set xtics add (7.5)
set mxtics 5
Major tics at 0,5,7.5,10, minor tics at 1,2,3,4,6,7,8,9
set logscale y
set format y ""
set ytics 1e-6, 10, 1
set ytics add ("1" 1, ".1" 0.1, ".01" 0.01, "10^-3" 0.001, \
"10^-4" 0.0001)
set mytics 10
Major tics with special formatting, minor tics at log positions
By default, minor tics are off for linear axes and on for logarithmic axes. They inherit the settings for
axis|border and {no}mirror specified for the major tics. Please see set xtics (p. 143) for information
about these.
70.41 My2tics
Minor tic marks along the y2 (right-hand) axis are controlled by set my2tics. Please see set mxtics
(p. 116).
70.42 Mytics
Minor tic marks along the y axis are controlled by set mytics. Please see set mxtics (p. 116).
70.43 Mztics
Minor tic marks along the z axis are controlled by set mztics. Please see set mxtics (p. 116).
