Hello,

Thanks for your answer, I am sorry for not putting the code anyways it was
intuitive of you to guess what I was asking :) ,  the legend works for every
new graph but when i tried to modify the code by using num2str for every new
graph it doesnt convert the number to string is there a work around for this
problem?

Here is what i am doing

 P=num2str(alpha);
semilogx(f,20*log10(abs(H)),";P;",'linewidth',3)

try

P=";" + num2str(alpha) + ";" ;
semilogx(f,20*log10(abs(H)), P ,'linewidth',3)

or

P=num2str(alpha);
semilogx(f,20*log10(abs(H)),";"+P+";",'linewidth',3)

this is untested by me but give it a try

 and this is what i get in the graph
