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.

There is nothing wrong with the code you have shared. Is there anything unique about your install? OS?

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. :-)
