There is no dedicated axes property to do that.

You may use xstring() as below.
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)

clf
plot2d()
ax  =  gca();
ax.box  =  "off";
b  =  ax.data_bounds

xstring(b(1),b(4),"↑")
set(gce(),  "clip_state","off",  "text_box_mode","centered",  "font_size",4)

xstring(b(2),b(3),"→")
set(gce(),  "clip_state","off",  "text_box_mode","centered",  "font_size",4)
