Syntax:
set terminal aifm {<color>} {"<fontname>"} {<fontsize>}
color is either color or monochrome; "fontname" is the name of a valid PostScript font; fontsize is the size of the font in PostScript points, before scaling by the set size command. Selecting default sets all options to their default values: monochrome, "Helvetica", and 14pt.
Since AI does not really support multiple pages, multiple graphs will be drawn directly on top of one another. However, each graph will be grouped individually, making it easy to separate them inside AI (just pick them up and move them).
Examples:
set term aifm set term aifm 22 set size 0.7,1.4; set term aifm color "Times-Roman" 14
