Right. Sorry, I wasn't precise in my description.

set term windows enhanced font "arial,9"
set label 1 "e^{i{/symbol p}}=-1" at graph 0.5,0.5 font "Times,15"
set label 2 "{/Courier=15 e^{i{/symbol p}}=-1}" at graph 0.5,0.6
plot sin(x) with linespoints

Here the second label works, but the first doesn't.

>From debugging I saw that the flow was:
     term.c: place_labels(), calling
 gadgetgs.c: write_label(), calling
     term.c: write_multiline()
now in write_multiline() there is the call to set_font in line 965

    /* EAM 9-Feb-2003 - Set font before calculating sizes */
    if (font && *font && t->set_font)
	(*t->set_font) (font);

which applies the explicit font for label 1. Ok.
Then write_multiline() calls WIN_enhanced_put_text() in win.trm where
I read in line 895

	/* This will restore the default font 
	   and update WIN_font and WIN_fontsize */
	WIN_set_font(NULL);

which then revokes the previously set fontname/size.

However, I see that enhanced_recursion() also has a parameter
'fontname' which is set to be NULL from within WIN_enhanced_put_text()
which, in line 2755 of enhanced_recursion()

	default:
	    /*{{{  print it */
	    (term->enhanced_open)(fontname, fontsize, base, widthflag, showflag, overprint);
	    (term->enhanced_writec)(*p);

leads to NULL passed in the variable fontname to WIN_enhanced_open()
consequently leading to the default fontname being substituted *again*.

And then I got a bit confused as to the many calls to set the 
fontname/size.

Hmm, I guess it's not that simple to solve this.
