How can I create threshold line red color?

load('Vepdata3.mat');

hLen=length(h);

figure;

plot(EEGdata); %plot EEGdata

xlabel('time(s)');

ylabel('Amplitude(microA)');

hold on;

threshold=40;

thresholdLine=40; % Draw a horizontal line at y = 40;

plot(thresholdLine,'r-');

title('thresholdLine');

xlabel('time(s)');

ylabel('Amplitude(microA)');

Try yline

yline(threshold, 'Color', 'r', 'LineWidth', 2);

instead of what you have

thresholdLine=40; % Draw a horizontal line at y = 40;
plot(thresholdLine,'r-');
