adding two ticks to form a horizontal line

How do I add two ticks in the plot editor so that it gives me a perfect horizontal straight line?

Answer 1

if you want to add a horizontal line to you plot you can use yline. if you want a ytick at that specific value you can write

yline(3.3614);
yticks(unique([yticks() 3.3614]));

i have written a code for many figures in a single plot,so i have added hold on command a few times ,so where should i add this 2 lines?

at the end of my code?

[shahriar sowad]

here is my code,

x0=reshape(b',[1,7001]);

t=linspace(0,1,7001);

Y=fft(b);

Yabs=abs(Y);

plot(a,'b');

hold on

x1=reshape(d',[1,7001]);

t=linspace(0,1,7001);

Y1=fft(x1);

Y1abs=abs(Y1);

plot(Y1abs,'g');

hold on

x2=reshape(f',[1,7001]);

t=linspace(0,1,7001);

Y2=fft(x2);

Y2abs=abs(Y2);

plot(Y2abs,'r');

hold on

x3=reshape(h',[1,7001]);

t=linspace(0,1,7001);

Y3=fft(x3);

Y3abs=abs(Y3);

plot(Y3abs,'k');

hold on

x4=reshape(j',[1,7001]);

t=linspace(0,1,7001);

Y4=fft(x4);

Y4abs=abs(Y4);

plot(Y4abs,'y');

hold on

x5=reshape(l',[1,7001]);

t=linspace(0,1,7001);

Y5=fft(x5);

Y5abs=abs(Y5);

plot(Y5abs,'m');

yes, add the two lines at the end of your code.

note that you just need one 'hold on' command, this will have the effect that all later plots are added to the current figure

it is showing error as undefined function yline
