Syntax:
set terminal aqua {<n>} {title "<wintitle>"} {size <x> <y>} {font "<fontname>{,<fontsize>}"} {linewidth <lw>}"} {{no}enhanced} {solid|dashed} {dl <dashlength>}}
where 4#4n5#5 is the number of the window to draw in (default is 0), 4#4wintitle5#5 is the name shown in the title bar (default "Figure 4#4n5#5"), 4#4x5#5 4#4y5#5 is the size of the plot (default is 846x594 pt = 11.75x8.25 in).
Use 4#4fontname5#5 to specify the font (default is "Times-Roman"), and 4#4fontsize5#5 to specify the font size (default is 14.0 pt).
The aqua terminal supports enhanced text mode (see enhanced (p. )), except for overprint. Font support is limited to the fonts available on the system. Character encoding can be selected by set encoding and currently supports iso_latin_1, iso_latin_2, cp1250, and UTF8 (default).
Lines can be drawn either solid or dashed, (default is solid) and the dash spacing can be modified by 4#4dashlength5#5 which is a multiplier 5#5 0.
