or [no]raise are specified, they will override command line options and Xresources. Setting one of these<br />
options takes place immediately, so the behaviour of an already running driver can be modified.<br />
The option title "" will supply the title name of the window for the current plot window<br />
or plot window if a number is given. Where (or if) this title is shown depends on your X window<br />
manager.<br />
The size or aspect ratio of a plot may be changed by resizing the gnuplot window.<br />
Linewidths and pointsizes may be changed from within gnuplot with set linestyle.<br />
For terminal type x11, gnuplot accepts (when initialized) the standard X Toolkit options and resources<br />
such as geometry, font, and name from the command line arguments or a configuration file. See the X(1)<br />
man page (or its equivalent) for a description of such options.<br />
A number of other gnuplot options are available for the x11 terminal. These may be specified either<br />
as command-line options when gnuplot is invoked or as resources in the configuration file ".Xdefaults".<br />
They are set upon initialization and cannot be altered during a gnuplot session. (except persist and<br />
raise)<br />
36.59.78.1 X11 fonts Upon initial startup, the default font is taken from the X11 resources as set<br />
in the system or user .Xdefaults file or on the command line.<br />
Example:<br />
gnuplot*font: lucidasans-bold-12<br />
A new default font may be specified to the x11 driver from inside gnuplot using<br />
‘set term x11 font ""‘<br />
The driver first queries the X-server for a font of the exact name given, for example set<br />
term x11 font "lucidasans-10". If this query fails, then it tries to interpret as<br />
",,," and to construct a full X11 font name of the form<br />
-*----*-*--*-*-*-*-*-<br />
is the base name of the font (e.g. Times or Symbol)<br />
is the point size (defaults to 12 if not specified)<br />
is ‘i‘ if =="italic" ‘o‘ if =="oblique" ‘r‘ otherwise<br />
is ‘medium‘ or ‘bold‘ if explicitly requested, otherwise ‘*‘<br />
is set based on the current character set (see help for ‘set encoding‘).<br />
So set term x11 font "arial,15,italic" will be translated to -*-arial-*-i-*-*-15-*-*-*-*-*-iso8859-1<br />
(assuming default encoding). The , , and specifications are all optional. If you<br />
do not specify or then you will get whatever font variant the font server offers first.<br />
The driver also recognizes some common PostScript font names and replaces them with possible X11 or<br />
TrueType equivalents. This same sequence is used to process font requests from set label.<br />
36.59.78.2 Command-line options In addition to the X Toolkit options, the following options<br />
may be specified on the command line when starting gnuplot or as resources in your ".Xdefaults" file<br />
(note that raise and persist can be overridden later by set term x11 [no]raise [no]persist):<br />
‘-mono‘<br />
‘-gray‘<br />
‘-clear‘<br />
‘-tvtwm‘<br />
‘-raise‘<br />
‘-noraise‘<br />
‘-noevents‘<br />
‘-persist‘<br />
forces monochrome rendering on color displays.<br />
requests grayscale rendering on grayscale or color displays.<br />
(Grayscale displays receive monochrome rendering by default.)<br />
requests that the window be cleared momentarily before a<br />
new plot is displayed.<br />
requests that geometry specifications for position of the<br />
window be made relative to the currently displayed portion<br />
of the virtual root.<br />
raises plot window after each plot.<br />
does not raise plot window after each plot.<br />
does not process mouse and key events.<br />
plot windows survive after main gnuplot program exits.
