gnuplot/eps/mono

[A. Scottedward Hodel]

There's been some discussion on the list about gnuplot generating  
color eps/epslatex plots when mono is requested.  I used the -debug  
option in the print script and found that if I removed the text
	linecolor rgb "#0000ff"
from the second set style line command then I get a black-and-white  
plot, whereas the rgb command seems to set gnuplot back to color  
plotting if it's left t here.

I can't say whether that's a bug in gnuplot or not.    If routine  
__go_draw_axes__.m it can be informed of the "mono" option so that it  
can omit the linecolor command, that should fix at least this part of  
the problem.

octave code:
  xx = linspace(0,5,5);
octave:23> yy = sin(xx);
octave:24> plot(xx,yy);
octave:25> print -deps -mono jnk.eps -debug
