This terminal relies on AquaTerm.app for display on Mac OS X.
Syntax:
set terminal aqua {<n>} {title "<wintitle>"} {size <x> <y>}
{font "<fontname>{,<fontsize>}"}
{{no}enhanced} {solid|dashed} {dl <dashlength>}}
where <n> is the number of the window to draw in (default is 0), <wintitle> is the name shown in the title bar (default "Figure <n>"), <x> <y> is the size of the plot (default is 846x594 pt = 11.75x8.25 in).
Use <fontname> to specify the font to use (default is "Times-Roman"), and <fontsize> to specify the font size (default is 14.0 pt). The old syntax {fname "<fontname>"} {fsize <fontsize>} is still supported.
The aqua terminal supports enhanced text mode (see `enhanced`), except for overprint. Font support is limited to the fonts available on the system. Character encoding can be selected by encoding and currently supports iso_latin_1, iso_latin_2, cp1250, and default which equals UTF8.
Lines can be drawn either solid or dashed, (default is solid) and the dash spacing can be modified by <dashlength> which is a multiplier > 0.
