Hi I have lat and log with time (mm:ss) I would like to make 2d plot(lat,long) and add a time label to each point (in mm:ss format). Any idea how to get it? thank you

text() the time label giving the coordinates of the point.
For example, with HH and MM being the vectors of the hours and minutes,
labstr = arrayfun( @(hh, mm) sprintf( '%02d:%02d', hh, mm), HH, MM, 'uniform', 0);
text( lat(:), long(:), labstr, 'HorizontalAlignment', 'right')
That should draw all of the labels at the same time.

The problem with saying that the vector T contains time(MM:SS) is that you did not describe the datatype of T. Is it a cell array of character vectors? Is it a string array (R2016b or later)? Is it a vector of datetime() objects? Is it a vector of datenum? Is it a vector where the integer portion is the number of hours and the decimal part is fraction of hours?
