How to remove units from a plot?

Hello! How can I remove the unit "seconds" for the x label? I need to use the unit in another language. I searched everywhere and I coul not find a helpfull answer. Thank you!

possible share your code, so we could help you better

At the moment I suspect it would be a matter of changing the axes xlabel()

I tried to use xlabel('text'), but the output label is: text (seconds). I wish I could delete the "seconds".

I need to compute the system response for a square wave input.

num = [37.5 13875 1125000]; den = [2.45 38.125 6205 1125000];
G = tf(num,den);
t = 1:0.01:5;
sq_wave = 0.01*square(2*pi*0.3.*t,50);

%% plot the response
lsim(G,sq_wave,t)

The plot goes automatically with the x label "Time (seconds)".

Matlab sets automatically the unit seconds.

I would still like to know how i get rid of the units...? Its very annoying that they cannot be removed.

num = [37.5 13875 1125000]; den = [2.45 38.125 6205 1125000];
G = tf(num,den);
t = 1:0.01:5;
sq_wave = 0.01*square(2*pi*0.3.*t,50);
%% plot the response

fig = figure();

lsim(G,sq_wave,t);

Warning: Simulation will start at a nonzero initial time.

L = findall(fig, 'String', 'Time (seconds)');
L.String = 'Time';

This was a weird one. It turns out that the labels that are visible are in a separate axes that is marked Visible off and HandleVisibility off. I have no idea why they would bother to do that.

You can try to save and re-plot the output of the graph, then use xlabel to solve your problem.

[z,x,y]=lsim(G,sq_wave,t)
plot(x,y)
xlabel('time')

Hope that's helpful!

It worked. Thanks so much!
