Plotting in Black and white with different linestyles in gif or png

[Markus E. <ei...@in...>]

When I generate several plots and print them to GIF or PNG the plots 
have the same style but different colors.
This is useless for colorless papers, so the plots should have different 
styles instead (dots, x,o). Can I somehoe switch from color to BW mode?

An sample line from my code is:

set term gif size 640,400

set output 'M1_cur_ctrl.gif'
plot filename using ($1):(2*pi/5-((int($2)%147)/147.2*2*pi/5)-pi/5) axes 
x1y1 title 'TARGET_M1' with lines,\
'' u 1:((abs(int($4)%147)/147.2*pi/5)) axes x1y1 title 'ERROR_M1' with 
lines,\
'' u 1:14 axes x1y2 title 'CURRENT_M1' with lines

Thanks for your support. I am a real gnuplot noob ;-)
