how can i divide a plot into ranges of different length

hello, i have a plot of different straight lines, and i would like to divide it into different ranges of x values, but that has different lengths so i can use these ranges in a for loop later.

It's a bit unclear what you mean by the question. You could divide the set of data into segments using logical indexing. For example

x = 0:0.1:2*pi;
y = sin(x);
s{1} = x > pi;
s{2} = x <= pi;

Now you can plot the first and second part separately.

plot(x(s{1}),y(s{1}),'r',...
  x(s{2}),y(s{2}),'b')

It's also trivial to access the different segments in a loop.
