Need plot for time rather than samples

I am plotting a signal and need to do it with time on the X-axis. This is the code I used

Load Signal %load the appropriate signal

Fs = 200 ; %setting sample rate to 200

T = 1/Fs; %converting the sample to time

L1=length(Signal) ; %length of my signal (in this case its 4933)

plot(t,Signal);

when I do this I get an error saying not the same vector length.

Sorry for being a coding noob and thanks for you time :)

If the time vector does not already exist, create it —

Signal = sin(2*pi*(0:999)*0.01) + randn(1, 1000);   % Create 'Signal'
Fs = 200    ;                                       %setting sample rate to 200
Ts = 1/Fs;                                          %converting the sample to time
L1=length(Signal)  ;                                %length of my signal (in this case its 4933)
t = linspace(0, L1, L1)*Ts;                         % Create Time Vector
dt = t(2) - t(1)                                    % Verify Correct Sampling Interval (Delete Later)

dt = 0.0050

figure
plot(t,Signal)
grid

Experiment to get different results.

Absolute genius. Once I read your code it made so much sense. Thanks this helped me tons
