I am plotting the power spectrum from 16 channels. PSD was calculated using the pwelch function and its output has 3 dimensions: (Channels) x (Frequency index) x (Trial). Is there a way to produce the legend (data 1, data 2,...) with the channel numbers using a for loop, in order to avoid writing down all 16 labels?
thank you!
Here is what i get by the way:
figure(1), hold on
plot(f, mean(pwrsignal(:,:,:), 3), 'LineWidth', 2)
xlim([0 200])
legend
