How to Label a Series of Points on a Plot in MATLAB
If you have a vector of coordinate for a set of points, you might want to differentiate those points. To do that a concept called logical indexing will help you pull out a subset of those points easily.

In this MATLAB video we show how you can manipulate the clim property of an axis to determine the points that an image will saturate the colormap. This is often a better choice than making a strange colormap to get the same effect.
