Look, I am plotting some line using a loop. The point is that these lines has totally different color with the legend colors.

D=table(Y,X,meanD)

writetable(D,'D.txt')

hold on

plot(Y,X,'o','DisplayName','0.3')

plot(Y,meanD,'*','DisplayName','0.3')

legend

Ivan, when you plot multiple lines like this and want to put a legend into the figure (or want to modify the lines)

use the plot-handles returned by plot:

x = 0:10;
y = randn(5,numel(x));
ph1 = plot(x,y(1:2,:),'-','linewidth',2);
hold on
ph2 = plot(x,y(3:5,:),'--')
legend([ph1(:);ph2(:)],'1','2','3','4','5')

HTH

Excuse me , if I would like to add a specific letter in the legend what I should do ?

I am using a loop in order to "pick" the names for the legend and I use these commands:

np=filenames
legend ([ph1(:);ph2(:)],np{1:n} )

np has these names:

TEST1, TEST2, TEST3.

I would like to put a character, eg letter "M", in the "legend" command, in order to my final legend in the plot to have:

TEST1 M

TEST2 M

TEST3 M

Could you help me?

[Bjorn Gustavsson]

Ivan, you could do something like this programatically:

for iFiles = numel(np)
    legstr{iFiles} = [np(iFiles).name,' M']; % or with sprintf('%s M',np(iFiles).name);
end
legend([ph1(:);ph2(:)],legstr{:})

When I've come that far I usually become pragmaticall and start to hard-code the legend-strings, it comes down to how many times you will re-run this with other labelings...

I have tried your solution but it shows me these:

Error using legend

Inputs must be the same size or either one can be a scalar.

What I have to do in order to solve it?
