GNUPlot Manual

80 gnuplot 4.0 36 SET-SHOW
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.
Minor tics can be used only with uniformly spaced major tics. Since major tics can be placed arbitrarily
by set {x|x2|y|y2|z}tics, minor tics cannot be used if major tics are explicitly set.
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. 149) for information
about these.
36.40 My2tics
Minor tic marks along the y2 (right-hand) axis are controlled by set my2tics. Please see set mxtics
(p. 79).
36.41 Mytics
Minor tic marks along the y axis are controlled by set mytics. Please see set mxtics (p. 79).
36.42 Mztics
Minor tic marks along the z axis are controlled by set mztics. Please see set mxtics (p. 79).
36.43 Offsets
Offsets provide a mechanism to put a boundary around the data inside of an autoscaled graph.
Syntax:
set offsets , , ,
unset offsets
show offsets
Each offset may be a constant or an expression. Each defaults to 0. Left and right offsets are given in
units of the x axis, top and bottom offsets in units of the y axis. A positive offset expands the graph in
the specified direction, e.g., a positive bottom offset makes ymin more negative. Negative offsets, while
permitted, can have unexpected interactions with autoscaling and clipping.
Offsets are ignored in splots.
Example:
set offsets 0, 0, 2, 2
plot sin(x)
This graph of sin(x) will have a y range [-3:3] because the function will be autoscaled to [-1:1] and the
vertical offsets are each two.
36.44 Origin
The set origin command is used to specify the origin of a plotting surface (i.e., the graph and its
margins) on the screen. The coordinates are given in the screen coordinate system (see coordinates
(p. 18) for information about this system).
Syntax:
set origin ,
