I have scatter plot. I need draw line or something similar between two point if their x distance is longer than 2. I draw to picture.

Thank You!

You can easily find the indices of such locations (assuming x and y are sorted along x):

x=[linspace(-16,-8,200) linspace(-5.5,2,200)];
y=rand(size(x));
ind=find(diff(x)>=2);

plot(x,y,'.b'),hold on
for n=1:numel(ind)
    plot(x(ind(n)+[0 1]),y(ind(n)+[0 1]),'b');
end
hold off

It works!

Thank You so much!
