How to name/number each line graph in Y axis, instead of the 1-9 numbers?

I want to name the line graphs in y axis like this (in red).

Program as follows

 for i=1:9
    g=GG(:,i)+i;
    plot(X,g)
    hold on
end 

end

[Jos (10584)]

use the function text

text(X, Y, STR)

will place the string STR at the location (X,Y) on the current axes.

Hi, I want to display the -0.8 to 0.8 in the Y axis instead of the 1 to 9 numbers.

[Jos (10584)]

Two options,

1) change the tick labels

set(gca,'ylim',[0 10],'ytick',1:9,'yticklabel',arrayfun(@(k) sprintf('%-.1f',k),-0.8:0.2:0.8,'un',0))

2) change the y-values

I would set the DisplayName property of each line as I created it, then call legend with the 'show' option afterwards.

M = magic(5);
for k = 1:size(M, 2)
  plot(M(:, k), 'DisplayName', num2str(k, 'M(:, %d)'))
  hold on
end
legend show
