At my workplace, we have MatLab R2012a. I have been asked to plot a graph and add the 'date and time' on the top or bottom of the graph - timestamp. How it can be done by using either the editor command or the graph.s title?
I have tried text(0.5,0.5, datestr(clock), 'HorizontalAlignment', 'left', 'VerticalAlignment','top') and the command is accepted but nothing shows up on the graph?
Please help. Thanks.

Ran in:
I no longer have access to R2012a, so I cannot test this with it.
The code you posted works correctly in R2022a, however R2012a may require a separate sprintf call —
title(sprintf('%s', datestr(clock)))
See if that works.
All of these work correctly in R2022a:
text(0.5,0.5, datestr(clock), 'HorizontalAlignment', 'left', 'VerticalAlignment','top')
title(datestr(clock))
ylabel(sprintf('%s', datestr(clock)))
.

Hello Star and Chris,
The OS is Windows 10, so don't know why it doesn't show up? However, the other code you share works. Thank you! I also needed to add a Test Name to it.
The code now has the 'Test Name and Timestamp' coming up automatically now!! I've been wrestling with this for over a month. I do have MatLab 2022 at home through DAU Coursera but it takes time to purchase a new license. So, I've been bouncing between 2012 to 2022...LOL
title(sprintf('TITLE: %s DATE: %s', 'XYZ', datestr(clock)))
Thank you so much Star! You have made my day. :-)
