It's worth noting that the OP was using the second example on the online
documentation
<https://octave.sourceforge.io/octave/function/datetick.html>
as a guide which also incorrectly transposes the first two inputs. I have
submitted a bug report to the bug tracker
<https://savannah.gnu.org/bugs/?49954>.
I'm more than happy to help fix this documentation error if someone can
point me towards the best way to contribute changes towards the online
documentation.

As explained in the bug tracker [1] the change of the online documentation
[2] (actually it is a documentation maintained by Octave forge, the official
Octave documentation for the latest release is found at [3]) depends on a
page update by Carnë.
