I have 3 plots on the same figure but legend doesn't show the right color for each plot.
y=1:10;
color_=['r', 'b'];
for i=1:2
if i==1
j=1;
elseif i==2
j=6;
end
plot(y(j:j+4),color_(i));
hold on
plot([0 10],[5 5],'g');
end
legend('plot1','plot2','line');

h1 = plot(x1,y1,'r');
hold on
h2 = plot(x2,y2,'b');
legend([h1,h2],'plot1','plot2')
The line color used for legend() will be the same as the line color used on the graph.

sice i was using a loop, i did this thing:
h=zeros(2);
colors=['r','g']
for i=1:2
h(i)=plot(x1,y1,colors(i))
legend([h(1),h(2)],'plot1','plot2')
end
