Syntax:
set term wxt {}
{size ,}
{{no}enhanced}
{font }
{title "title"}
{{no}persist}
{{no}raise}
{{no}ctrl}
{close}
Multiple plot windows are supported: set terminal wxt directs the output to plot window number
n.
The default window title is based on the window number.
keyword "title".
This title can also be specified with the
Plot windows remain open even when the gnuplot driver is changed to a different device. A plot window
can be closed by pressing the letter ’q’ while that window has input focus, by choosing close from a
window manager menu, or with set term wxt close.
The size of the plot area is given in pixels, it defaults to 640x384. In addition to that, the actual size
of the window also includes the space reserved for the toolbar and the status bar. When you resize a
window, the plot is immediately scaled to fit in the new size of the window. Unlike other interactive
terminals, the wxt terminal scales the whole plot, including fonts and linewidths, and keeps its global
aspect ratio constant, leaving an empty space painted in gray. If you type replot, click the replot icon
in the terminal toolbar or type a new plot command, the new plot will completely fit in the window
and the font size and the linewidths will be reset to their defaults.
The active plot window (the one selected by set term wxt ) is interactive. Its behaviour is shared
with other terminal types. See mouse (p. 113) for details. It also has some extra icons, which are
supposed to be self-explanatory.
This terminal supports an enhanced text mode, which allows font and other formatting commands
(subscripts, superscripts, etc.) to be embedded in labels and other text strings. The enhanced text
mode syntax is shared with other gnuplot terminal types. See enhanced (p. 186) for more details.
is in the format "FontFace,FontSize", i.e. the face and the size comma-separated in a single
string. FontFace is a usual font face name, such as ’Arial’. If you do not provide FontFace, the wxt
terminal will use ’Sans’. FontSize is the font size, in points. If you do not provide it, the wxt terminal
will use a size of 10 points.
For example :
set term wxt font "Arial,12"
set term wxt font "Arial" # to change the font face only
set term wxt font ",12" # to change the font size only
set term wxt font "" # to reset the font name and size
The fonts are retrieved from the usual fonts subsystems. Under Windows, those fonts are to be found
and configured in the entry "Fonts" of the control panel. Under UNIX, they are handled by "fontconfig".
Pango, the library used to layout the text, is based on utf-8. Thus, the wxt terminal has to convert from
your encoding to utf-8. The default input encoding is based on your ’locale’. If you want to use another
encoding, make sure gnuplot knows which one you are using. See encoding (p. 99) for more details.
Pango may give unexpected results with fonts that do not respect the unicode mapping. With the
Symbol font, for example, the wxt terminal will use the map provided by http://www.unicode.org/ to
translate character codes to unicode. Pango will do its best to find a font containing this character,
looking for your Symbol font, or other fonts with a broad unicode coverage, like the DejaVu fonts.
Note that "the Symbol font" is to be understood as the Adobe Symbol font, distributed with Acrobat
Reader as "SY .PFB". Alternatively, the OpenSymbol font, distributed with OpenOffice.org as
"opens .ttf", offers the same characters. Microsoft has distributed a Symbol font ("symbol.ttf"), but
it has a different character set with several missing or moved mathematic characters. If you experience
problems with your default setup (if the demo enhancedtext.dem is not displayed properly for example),
