Syntax:
set terminal be {reset} {<n>}
Multiple plot windows are supported: set terminal be 5#5n6#6 directs the output to plot window number n. If n6#60, the terminal number will be appended to the window title and the icon will be labeled gplt 5#5n6#6. The active window may distinguished by a change in cursor (from default to crosshair.)
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, or by choosing close from a window manager menu. All plot windows can be closed by specifying reset, which actually terminates the subprocess which maintains the windows (unless -persist was specified).
Plot windows will automatically be closed at the end of the session unless the -persist option was given.
The size or aspect ratio of a plot may be changed by resizing the gnuplot window.
Linewidths and pointsizes may be changed from within gnuplot with set linestyle.
For terminal type be, gnuplot accepts (when initialized) the standard X Toolkit options and resources such as geometry, font, and name from the command line arguments or a configuration file. See the X(1) man page (or its equivalent) for a description of such options.
A number of other gnuplot options are available for the be terminal.
These may be specified either as command-line options when gnuplot is
invoked or as resources in the configuration file ".Xdefaults". They are
set upon initialization and cannot be altered during a gnuplot session.
