GNUPlot Manual

36 SET-SHOW gnuplot 4.0 145
36.68 Urange
The set urange and set vrange commands set the parametric ranges used to compute x, y, and z
values when in splot parametric mode. Please see set xrange (p. 148) for details.
36.69 Variables
The show variables command lists all user-defined variables and their values.
Syntax:
show variables
36.70 Version
The show version command lists the version of gnuplot being run, its last modification date, the
copyright holders, and email addresses for the FAQ, the gnuplot-info mailing list, and reporting bugs–in
short, the information listed on the screen when the program is invoked interactively.
Syntax:
show version {long}
When the long option is given, it also lists the operating system, the compilation options used when
gnuplot was installed, the location of the help file, and (again) the useful email addresses.
36.71 View
The set view command sets the viewing angle for splots. It controls how the 3-d coordinates of the
plot are mapped into the 2-d screen space. It provides controls for both rotation and scaling of the
plotted data, but supports orthographic projections only. It supports both 3D projection or orthogonal
2D projection into a 2D plot-like map.
Syntax:
set view { {,{}{,{}{,}}} | map }
show view
where and control the rotation angles (in degrees) in a virtual 3-d coordinate system
aligned with the screen such that initially (that is, before the rotations are performed) the screen horizontal
axis is x, screen vertical axis is y, and the axis perpendicular to the screen is z. The first rotation
applied is around the x axis. The second rotation applied is around the new z axis.
Command set view map is used to represent the drawing as a map. It can be used for contour plots,
or for color pm3d maps. In the latter, take care that you properly use zrange and cbrange for input
data point filtering and color range scaling, respectively.
is bounded to the [0:180] range with a default of 60 degrees, while is bounded to
the [0:360] range with a default of 30 degrees. controls the scaling of the entire splot, while
scales the z axis only. Both scales default to 1.0.
Examples:
set view 60, 30, 1, 1
set view ,,0.5
The first sets all the four default values. The second changes only scale, to 0.5.
See also set ticslevel (p. 142).
36.72 Vrange
The set urange and set vrange commands set the parametric ranges used to compute x, y, and z
values when in splot parametric mode. Please see set xrange (p. 148) for details.
