Thread Subject: MATLAB legends

Hi all, i m stuck in a situation that i would like to share in this forum. I have generated a figure in MATLAB having multiple curves. Legends of this curve were shown through the GUI "insert legend" button. Now i want to hide some of the legends while showing the others. Anyone help will be appreciated.

Regards...

Insert a legend in the code itself.

LEGEND(H,string1,string2,string3, ...)

where H is the handle(s) of the plots and the strings correspond to the handles.

for example;

t=0:.1:4
y=cos(t)

hold on
h1=plot(t,y,'r')
h2=plot(t,y.*2,'g')
h3=plot(t,y./2,'b')

legend([h1,h3],'cos','cos/2')

plot (rand (5,5))
legend show
leg = findobj (gcf, 'tag', 'legend')
set (leg, 'String', {'data1' 'data4' 'data5'})

The issue is that i have already generated the figures and it requires 4 to 5 hrs to generate them. On top of that, i don't have the values or reading of the generated figures, so what possible method can i follow which can be applicable on the figure itself?

Osama, which line of

plot (rand (5,5))
legend show
leg = findobj (gcf, 'tag', 'legend')
set (leg, 'String', {'data1' 'data4' 'data5'})

don't you understand?
