How to split into small pieces of ranges of this graph?

How to split into small pieces of ranges from this graph?

Range=[ ] ?

I am not sure how to cut these graphs into smaller parts to analyze them.

I keep getting this error!!

"Array indices must be positive integers or logical values."

this plots first the first half then the second

subplot 211 
plot(x(1:numel(x)/2),y(1:numel(y)/2))
subplot 212
plot(x(numel(x)/2:end),y(numel(y)/2:end))

you can also plot other ranges or segment, just indicate the proper indexes for x and y (if you have only one variable per plot then forget about the y).

for example, the following lines plot the first 100 points in 1 subplot, the second 100 are plotted in the other

subplot 211 
plot(x(1:100))
subplot 212
plot(x(101:200))

I want both to be splitting in the same range. How do i do that one?

[LO]

you probably mean this ?

range = [200:275];
subplot 211 
plot(x1(range))
subplot 212
plot(x2(range))

[SZ N]

yes, exactly!

So for example, How do i split for these marked portions on the picture below and so on? Im a little confused on how to get those values for the range [ ],so that i can split them into pieces so that i can align them?

[LO]

Well the values for range can be set arbitrarily by you or sequentially through a for loop For example if the ranges should be 50 points each

for n = 1:50:1000
range = n:n+49
end

Thank you so much for your help!

You're welcome! Just mark the answer accepted if it fits😊

If you simply want to zoom in and look at a narrower viewport window, you can set the left and right ends of the x axis with the xlim() function. For example to have the graph show only the plot between 0.2 and 0.4, do

xlim([0.2, 0.4]);

after you've called plot().
