Help with building plot

x=[1:2:50] % this x coordinate where I need to plot
X=[24 23 23 25 26] % values ​​where to be y
[~,psk]=min(Data) % matrix 200x10
for i=1:n % n = 10
y(i)=psk(i)-2
p=length(x);
Data=Data(1:p,i);
Y=Data(y(i):psk); 
end
plot(Data,x)

Hello! Help with this problem, when plotting the Data graph from x, my values ​​do not coincide much

I don't really know what you are trying to do, but this statement:

Data=Data(1:p,i);

in your loop collapses your 200x10 matrix down to a vector that overwrites your original data, so that 2nd time round the loop (if indeed it even gets that far) you will get an error because i = 2, but Data is size (25,1)
