How to use 'hold on' when plotting inside for loops
显示 更早的评论
I have two matrices Flow1(1:5) and RTL(i,:) or (i,5).
I want to plot Flow1 over RTL and I write the following.
for i=num_cat
plot(Flow1(1:5),RTL(i,:),'--go');
hold on
end
hold off
I saw a previous post here that said that this is the way to get all 7 lines in one plot when i = 7 let's say. However, with my code, I only get the last plot line and not all the others. What do I do wrong and how can I get all plots in one figure? Thanks!

Flow1 = rand(1,5) ;
RTL = rand(7,5) ;
num_cat = 7 ;
for i=1:num_cat
plot(Flow1(1:5),RTL(i,:),'--go');
hold on
end
hold off
you have use i = num_cat, so you were getting only one plot. It should be i = 1:num_cat

It is in green because you have mentioned the color green and fixed the markers too. You may check this:
Flow1 = rand(1,5) ;
RTL = rand(5,5) ;
num_cat = 5 ;
for i=1:num_cat
plot(Flow1(1:5),RTL(i,:));
hold on
end
hold off
legend({'i=1' ; 'i =2' ; 'i =3' ; 'i =4' ; 'i = 5'});
