Highlight data ouside of range

Hi all,

I have done a bit of looking around and havent been able to find any other people who have posted the same question. I have seen a few that were very similar but I am brand new to Matlab and didn't know how to apply those suggestions to my own needs.

I have a table of data, with the first columb denoting the time, and the second a voltage value measured at that time.

I am looking for a way to highlight the voltage values that have a difference of more than 50% than the value in the row directly above or below. Ideally when I plot these in a graph I would like a comment or some way for those values to be pointed out.

Any suggestions are welcome.

Thanks in advance!
