Label variation in graph not following variation

Hello guys, I am trying to variate my label with values of k from 0.1 to 0.9 for each line to show the dependance, but instead I always get k = 0.1. I attached the image and the data loaded in the plot function, and the code is shown below. Any help will be much appreciated.

data_name0='resultats/test_substrat.txt';
scan_trous_carres0 = importdata(data_name0);

for num_lambda=1:size_lambda
    shift_lambda=(num_lambda-1)*size_pk;
    for num_pk=1:size_pk
    shift_pk=(num_pk-1);
    A(num_pk,num_lambda)=scan_trous_carres0(1+shift_lambda+shift_pk,3);
    end  
end

for k = 0.1:0.9
        txt = ['X = ',num2str(k)];
        plot(lambda*1e6,A,'DisplayName',txt)
        legend show
        hold on
end

Try moving the legend show to after the for loop.

Hi Jose

Try using

for k=0.1:0.1:0.9

end

For more information refer for loop.

Hope it helps
