I designed a code to plot the data into a graph. It goes successfully but how can I rename the line in order according to the column in variable SNR_GNS and legend that into the figure? For example like the line in column 3 is renamed to G3 and line in column 10 is renamed to G10. Thanks

Images of code and data are really difficult to work with. Copying the sections of code/data as text makes it much easier to offer help.

Ran in:
It can be attained using legend() command, e.g.:
A = randi([-5 25], 5, 13);
B = 1:size(A,2);
plot(B,A, '-o', 'linewidth', 2)
xlabel('B')
ylabel('A series')
legend('A_1', 'A_2', 'A_3', 'A_4', 'A_5', 'Location', 'Best')
