Automatically assign legend name to set of data

Hello,

I have to plot different curves in a single graph. The number of the curves to plot can change. I would like to automatically rename the various curves by replacing the default name data1, data2, ecc...

Is there a simple way to do this?

I attach a simplified version of my code.

Thank you very much for your help

n=input('Enter the number of curves you want to fit:       ');
m=10;
x=zeros(m,1);
y=zeros(m,n);
x(:,1)=1:1:m;
for k=1:n
    for j=1:m
        y(j,k)=k+j;
    end
end
figure() 
semilogx(x(:,1),y(:,:),"o")
legend()
%how to rename y(:,1), y(:,2) etc... with y1, y2, ecc...???

hello

maybe this ?

now you have y1,y2,... in your legend

n=input('Enter the number of curves you want to fit:       ');
m=10;
x=zeros(m,1);
y=zeros(m,n);
x(:,1)=1:1:m;
for k=1:n
    for j=1:m
        y(j,k)=k+j;
    end
    leg_str{k} = ['y' num2str(k)];
end
figure() 
semilogx(x(:,1),y(:,:),"o")
legend(leg_str)
