Converting indices to time

Hi I am very new to the MatLab software, I have a vector size 1x5234400. For the recording software I am using, every 200 indices equates to 1 second, and I am trying to plot the time against the given values of the vector, but currently have the indices plotted against the given values of the vector. How can I go about creating a vector, using my conversion, to plot time against my values?

Thank you

This means your sampling rate is 200 Hz, so you can construct your time vector as

fs = 200;
t = (0:numel(x)-1)/fs;

then just do

plot(t,x)

assuming x is your signal

thank you so much!

If we want to plot the above signal with x_axis as standard time. What to do
