And Suppose i have 3 programs in one script. I have 4 subplot and each subplot holds 3 graph. In total, so i have 12 graph.
And i'm graphing them in each program instead of at the same paragraph.
For example :
(first program)
subplot(2,2,1)
plot(x,S)
hold on
subplot(2,2,2)
plot(x,E)
subplot(2,2,3)
plot(x,I)
subplot(2,2,4)
plot(x,R)
(second program)
subplot(2,2,1)
plot(x,S)
subplot(2,2,2)
plot(x,E)
subplot(2,2,3)
plot(x,I)
subplot(2,2,4)
plot(x,R)
(third program)
subplot(2,2,1)
plot(x,S)
subplot(2,2,2)
plot(x,E)
subplot(2,2,3)
plot(x,I)
subplot(2,2,4)
plot(x,R)
hold off
And i want to choose two legends.
The first legend is subplot(2,2,2) from the first program.
The second legend is subplot(2,2,2) from the third program.
How can i do this? Please help.

Just add the legend line in each "program".
(first program)
subplot(2,2,1)
plot(x,S)
hold on
subplot(2,2,2)
plot(x,E)
legend; % add legend to this subplot
subplot(2,2,3)
plot(x,I)
subplot(2,2,4)
plot(x,R)
(second program)
subplot(2,2,1)
plot(x,S)
subplot(2,2,2)
plot(x,E)
subplot(2,2,3)
plot(x,I)
subplot(2,2,4)
plot(x,R)
(third program)
subplot(2,2,1)
plot(x,S)
subplot(2,2,2)
plot(x,E)
legend; % add legend to this subplot
subplot(2,2,3)
plot(x,I)
subplot(2,2,4)
plot(x,R)
hold off

Here is my problem The legend "pj" must be blue, because i insert legend in the third program. But i don't know how this can be happen. Red color is from the first program that i've mentioned about
