What are possible issues if ''datetick()'' has no effect on the date format?

Good morning,

What are possible issues if ''datetick()'' has no effect on the date format in a plot? I already used ''datenum()'' but still ''datetick()'' doesn't work. Matlab apparently automatically chooses to use the format MM/DD, but I am looking for DD/MM/YY. Any ideas?

Thank you in advance!

Which release are you using, and what is class() of the first data you plot on your axis? Please show the datetick call.

Just found out (after searching for ages) that I called datetick twice and differenty, that's why it didn't work...

Thank you although!

May not see it, but unless you've a release prior to R2016b, I'd strongly suggest to dump the archaic datenum in favor of datetime which has builtin support for datetime formats in overloaded plot functions.

Early releases of datetime had overloaded plotting but internally did still use datenum.

I'm using R2007b...:/

But thank you!

wow, you need to update your release. There's been so many nice features implemented since 2007 :)
