Hi

Im trying to plot data that is store in the Serial Date Number format. Once plotted I would like to change the format to mm/dd HH:MM. The line of code that I'm using reads as follows:

datetick('x', 'mm/dd HH:MM', 'keeplimits', 'keepticks');

Unfortunately I get the following error:

??? Error using ==> datetick at 143
Unknown date format: mm/dd HH:MM

Error in ==> Plotter at 33
datetick('x', 'mm/dd HH:MM, 'keeplimits', 'keepticks');

If i switch the date format to one that has a predefined Date Format Number, the code executes seamlessly.

Any thoughts?

Thanks!

I do not see that problem in 2008b when I try that. I suggest you search the
bug reports.

I think you're telling fibs.
What you told us was the line of code is different from the line of
code Matlab quotes in the error message, where it appears that you
have omitted the apostrophe closing the date format string.

I may have inadvertently omitted the apostrophe when copying the text!
