How to obtain data which fall outside the limits of the scatter plots?

I have a set of data in a scattered diagram and I need to put limits to it. I want to collect values which lie outside the plot. Is there any code for that?

If the red line is computed at the same points as the other data, then simply

ix=ltbluepoints>redpoints;  % logical vector of those exceeding the redline
ptsOver=ltbluepoints(ix);   % and the values associated

"ltbluepoints" and "redpoints" are the variables you've used for those two portions of the figure.

You may be able to use the isoutlier function to identify those points with values that are too large.
