Investigating your example, you use the property clip_state and
set it to "off", clearly to allow the arrow to go a bit outside
the axes. I wondered whythis is necessary, considering that the
documentation says the default value is "off". But after running
some examples, I find "clipgrf" to be the default. Am I right?<br>

I have found a function xarrows which allows drawing arrows,

<br>
There is no dedicated axes property to do that.<br>
<br>
You may use xstring() as below.<br>
Bounds and arrows directions to use to set the arrows positions
will depend on the axes orientation (reverse or not) and
position (top/bottom | left/right)<br>
