How do I fix my legend?

Hello, I am creating a graph with mutiple for loops to obtain data, the problem at the moment is when I try to creat a legend corresponding to each specific value the it is only seeing the first for loop.

figure, hold on

for i=1:size(AB,1)

a1 = VAB(:,1)'*AB(i,:)';

b1 = VAB(:,2)'*AB(i,:)';

plot(a1,b1,'ko','LineWidth',3)

end

for i=1:size(CD,1)

c1 = VCD(:,1)'*CD(i,:)';

d1 = VCD(:,2)'*CD(i,:)';

plot(c1,d1,'bo','LineWidth',3)

end

for i=1:size(EF,1)

e1 = VEF(:,1)'*EF(i,:)';

f1 = VEF(:,2)'*EF(i,:)';

plot(e1,f1,'go','LineWidth',3)

end

for i=1:size(GH,1)

g1 = VGH(:,1)'*GH(i,:)';

h1 = VGH(:,2)'*GH(i,:)';

plot(g1,h1,'mo','LineWidth',3)

end

xlabel('PC1'),ylabel('PC2')

grid on, set(gca,'FontSize',15)

axis ([-1 1 -.1 .1])

legend('CAP','Capsiate','RTX','CPZ')

For every plot call, return a handle:

h1 = plot(a1,b1,'ko','LineWidth',3);
          . . .
h2 = plot(c1,d1,'bo','LineWidth',3);
          . . .
h3 = plot(e1,f1,'go','LineWidth',3);
          . . .
h4 = plot(g1,h1,'mo','LineWidth',3);

then in the legend call:

legend([h1 h2 h3 h4],'CAP','Capsiate','RTX','CPZ')

That should do what you want.

I cannot test it with your code, so I am posting this as UNTESTED CODE. It should work.

That worked perfectly, thank you so much!!!
