Several options may be set in the next driver.
Syntax:
set terminal next {<mode>} {<type> } {<color>} {<dashed>}
{"<fontname>"} {<fontsize>} title {"<newtitle>"}
where <mode> is `default`, which sets all options to their defaults; <type> is either `new` or `old`, where `old` invokes the old single window; <color> is either `color` or `monochrome`; <dashed> is either `solid` or `dashed`; "<fontname>" is the name of a valid PostScript font; <fontsize> is the size of the font in PostScript points; and <title> is the title for the GnuTerm window. Defaults are `new`, `monochrome`, `dashed`, "Helvetica", 14pt.
Examples:
set term next default
set term next 22
set term next color "Times-Roman" 14
set term next color "Helvetica" 12 title "MyPlot"
set term next old
Pointsizes may be changed with `set linestyle`."
