Great! That worked! Thanks so much. So, in regards to my other question, if I want to append the string 'nm/sec' to the very first value (-500000 to -500000 nm/sec) and also to the very last value (500000 to 500000 nm/sec) on the Y-axis, can I just get the first and last values of that column vector, such as:

mytitles = num2str(get(gca, 'YTick').)
title_length = length(mytitles)

mytitles(1) = [ mytitles(1) 'nm/sec' ]

mytitles(title_length) = [ mytitles(title_length) 'nm/sec' ]

% Then do the row to column vector transform
my_new_column_titles = mytitles'

% Now set the YTickLabels
set(gca, 'YTickLabel', my_new_column_titles )

Am I way off base here?
(Apologies for the pseudo code - I am more used to coding in Python and Perl)

Regards,
- Rob

Yah, that won't work for a number of reasons.

mytitles = cellstr(num2str(get(gca,'YTick').'));
mytitles{1} = [mytitles{1} ' nm/sec'];
mytitles{end} = [mytitles{end} ' nm/sec'];
set(gca, 'YTickLabel', mytitles);

However, the numbers then won't line up unless you have

set(gca,'YAxisLocation', 'right')


To get the tick label numbers to line up on the left,

set(gca, 'YTickLabel', char(mytitles), 'FontName', 'Courier')

Hi Walter,

Thanks so much for all the help. All the above worked, and I have learned more about Matlab cells and vector structures than I knew before. Much obliged!!!!

I think I am good for now. All the best,
